This formulation is safe for use in the garden and can be used on both fruit and vegetable bearing plants. It says its safe to use in gardens. In fact when you use Dominion as the label outlines the most common way to use it will be as a soil drench , the amount of active ingredient that gets into the plant will be minute and insignificant. In other words, the amount of chemical that will be present is so small, it can only affect insects and not mammals like people.

Apple & Crabapple Insects

Apricot, Prunus armeniaca is a deciduous tree in the family Rosaceae grown for its edible fruit. The apricot tree is has an erect growth habit and a spreading canopy. The leaves of the tree are ovate with a rounded base, pointed tip and serrated margin. The tree produces white to pink flowers, singly or in pairs, and a fleshy yellow to orange fruit. The apricot fruit is a drupe with skin that can be smooth or covered in tiny hairs depending on the variety and a single seed enclosed within a protective outer shell stone.

Apricot trees can reach 8—12 m 26—39 ft and can live anywhere between 20 and 40 years depending on variety and growth conditions. Content Content 1. Diseases - Fungal. Pests - Insects. See questions about Apricot. Ripening fruits. Apricot blossoms. Green fruit on tre. Apricot fruit on tree. Common Pests and Diseases Diseases. Armillaria mycelial mat. Armillaria fruiting Bodies.

Mushroom and mycelial fan characteristic of armillaria root rot Armillaria sp. If tree is infected after it has reached 5 years of age then typical symptoms include poor terminal growth and small leaves; around midsummer the whole tree suddenly collapses; in orchards trees usually die in a circular pattern; infected trees often have a fan-shaped white fungal mat growing between the bark and wood of the crown.

Management Once a tree is infected there is no treatment and it should be removed, fumigants do not control fungi in soil adequately; do not plant apricot in newly cleared forest or on the site of old orchards with a history of Armillaria.

Lesions on apricot fruit due to Monilinia fructicola, M. Top left-control; top centre-M. Death of young blossoms and associated twigs and leaves; small tan cankers with dark margins on twigs; gummy exudate at base of flowers; brown spore masses on flowers in humid conditions.

Management fungicide applications are required during bloom to control disease; application very important at red bud stage; applications should be made every 14 days or less if there is continued heavy rainfall. Cankers on branches, usually associated with a pruning wound which is several years old; discolored sapwood may extend abovwe and below canker; leaves on branches around canker may suddenly wilt as branch dies; leaves remain attached to branches; discoloured bark and inner wood; gummy amber exudate may be present.

Fungus enters fresh pruning wounds with rainfall weeks after pruning; emergence of disease most common in Fall or Winter. Management Infected limbs should be removed 1 ft below any internal symptoms before harvest; if pruning is conducted outwith this time a fungicide should be applied to the pruning wounds.

Brown discoloration of fruit under jacket occurring while flower parts still attached to fruit. Management Fungicide treatment applied at full bloom. Powdery mildew symptoms on apricot fruit. Round powdery white patches of fungal growth on fruits and leaves; rusty patches on fruits which turn brown and leathery and may crack. Management Apply fungicide during bloom and fruit development.

Symptoms of ripe fruit rot on apricot fruits. Dark brown circular spots on fruit; tan spore masses may be visible in center of spots; diseases fruit may not drop from tree.

Management A protective fungicide treatment may be necessary if heavy rains are forecast weeks prior to harvest. Rust symptoms. Pale yellow-green spots on both upper and lower leaf surfaces which are angular in shape and turn bright yellow in color; spots on lower leaf surface develop orange-red spores. Management Rust can be prevented by spraying trees with protective fungicides; application is usually carried out one, two and three months before harvest in areas prone to early season outbreaks of the disease and after harvest in areas where disease is less problematic or emerges later in the season.

Shot hole disease symptoms on a peach fruit caused by Wilsonomyces carpophilus. This disease on peach is distinguished by profuse gumming. Peach fruit displaying symptoms of infection with Shot Hole Disease Coryneum blight - Wilsonomyces carpophilus. Brown lesions with purple edge on fruit, twigs and buds; holes in leaves due to lesions which have dried and dropped out; brown lumps developing in the center of lesion visible with hand lens ; buds turning brown or black and exuding sap; tan lesions with brown margins which exude sap on twigs.

Management Application of Bordeaux mixture before rains in Fall are sufficient to protect dormant buds and twigs over winter. Withering of leaves on one or more spurs on 1 year old wood; leaves are dull and stunted; fruit small; older cherry trees do not recover from disease. Management Plant apricot in soil with no history of disease; keep trees adequately fertilized and watered.

Category : Bacterial. Cankers on twigs at bases of flower and leaf buds, in pruning wounds or at the base of spurs which exude amber colored gum; cankers spread upwards and form sunken areas in winter; if pathogen enters dormant buds they may be killed or open normally in Spring before collapsing in early Summer; infected buds may be symptomless.

Disease emergence favors high moisture and low temperatures in the spring; young trees particularly susceptible; trees grown in sandy soils that drain poorly are also susceptible. Management Ensure that a suitable apricot variety and rootstock is chosen based on geographic location and environmental conditions to prevent stress to tree which predisposes tree to canker disease; apply protective copper spray to trees before flowering; prune trees in early summer to decrease likelihood of infection.

Gall symptom. Crown gall. Infection with crown gall begins at the site of plant wounds; disease emergence is favored by poorly-drained, alkaline soils and previous feeding damage by nematodes. Management Chemical control of the disease is generally ineffective; an effective bacterial biological control is available for commercial production; cultural control methods include: planting only certified, disease-free material, planting apricot in well-draining soil, rotating infected fields with a non-host before apricot is planted and also using good sanitation practices.

Category : Oomycete. A tree with a Phytophthora crown rot infection caused by Phytophthora spp. Poor new growth; leaves chlorotic, small in size and sparse; fruit may be small, brightly colored and susceptible to sunburn; shoots may suffer from dieback and tree will often die within weeks or months of first signs of infection or decline gradually over several seasons; root crown may show signs of decay which develops into a canker; bark of infected crown tissue turns dark brown; cankers may occur on aerial parts of plant.

Severity of disease is linked to soil moisture content; water-saturated soils promote development of fungus. Management Plant trees on a small mound to promote drainage; avoid over-watering trees in spring; treat soil around newly planted trees with fungicide; minimize the frequency and duration of water saturated soil; trees should be propagated from resistant rootstock and application of appropriate systemic fungicides may provide some protection from the disease.

Symptoms of plum pox virus on apricot fruit and leaves. Infected fruit. Symptoms of plum pox on fruits and seed on apricot, showing brownish depressions and grooves on the surface.

Fruit symptoms of plum pox potyvirus infection on apricot. Leaf symptoms of plum pox potyvirus infection on apricot. Symptoms of plum pox virus on apricot fruits. Pale green chlorotic spots, rings and lines on leaves which appear in early summer; pale rings, lines and spots on fruit; fruit flesh dry and flavorless; fruit may be markedly deformed. Virus is transmitted by aphids but most common method of spread is diseased plant material.

Management Plant certified healthy material; remove infected trees from orchard; chemical sprays to control aphids may prolong spread of virus. European earwig adult. European earwig. Adult male and female European earwigs Forficula auricularia on a flower. Aggregation of earwigs at tip of plant. Mature trees generally tolerate damage well; if damage is caused to shoot tips of young trees then growth may be stunted; shallow, irregularly shaped areas may be present on fruit surface where insect has fed; insects are brown and shiny with a pincer-like structure at the end of the abdomen; can reach 1.

Management Remove all weeds from around tree bases; remove all pruning debris and loose bark around trees; wrapping trunks tightly with plastic wrap before nymphs emerge can stop them climbing up the tree; if using insecticide, apply early in Spring when earwigs begin to be active. Adult insect. Adult fruittree leafroller Archips argyrospila. Fruittree leafroller larva. Leaves of plant rolled and tied together with silk webbing; feeding damage to rolled leaves; defoliation of plant; silk webbing may also be present on fruits and fruits may have substantial scarring from feeding damage; larvae wriggle vigorously when disturbed and may drop from plant on a silken thread.

Management Monitor plants regularly for signs of infestation; remove weeds from plant bases as they can act as hosts for leafrollers; avoid planting pepper in areas where sugarbeet or alfalfa are grown nearby; Bacillus thuringiensis or Entrust SC may be applied to control insects on organically grown plants; apply sprays carefully to ensure that treatment reaches inside rolled leaves.

Green fruitworm. Large holes chewed in leaves and fruit; pale green caterpillars with white stripe down middle of back present on leaves and fruit. Insect usually overwinters as adult moth and undergoes only one generation per year.

Management If larva become damaging to trees then sprays of Bacillus thuringiensis will control young larvae effectively and can be applied during bloom; other organically acceptable control methods include application of Entrust; appropriate insecticides can be used as spot treatments if infestation is localized or applied shortly before, or during, petal fall.

Multiple Life Stages. Mealy plum aphid colony. High levels of infestation may cause stunted vegetative growth; black soot mold developing on leaves and branches; insect is small and soft-bodied, green in color and covered in white, mealy wax. Infestations usually appear in small pockets in orchards; insect eggs overwinter and hatch in Spring. Management Organically grown trees can be sprayed with neem oil to control aphid populations; chemical control of the aphid is rarely necessary.

Peach twig borer Anarsia lineatella adult. Peach twig borer larvae. Death of shoot tips; feeding damage to fruit, usually at stem end; larvae are dark brown and white with a black head; adult insect is a gray-brown moth. Peach twig borers overwinter as larvae in a specialized cell known as a hibernaculum; overwintering sites are located in rough areas of bark on 1 to 4 year old wood in crotch of limbs. Management Most effective method of treatment is well-timed applications of insecticide around time of bloom; organically acceptable insecticides include Bacillus thuringiensis or Entrust; infestations can also be treated with appropriate organophosphate or pyrethroid insecticides.

APPLE MAGGOT CONTROL

Download pdf. Fire blight is an important disease effecting pear and apple. Infections commonly occur during bloom or on late blooms during the three weeks following petal fall. Increased acreage of highly susceptible apple varieties on highly susceptible rootstocks has increased the danger that infected blocks will suffer significant damage. In Washington, there have been minor outbreaks annually since and serious damage in about percent of orchards in , , , , , , , , , andFire blight is caused by Erwinia amylovora , a gram-negative, rod-shaped bacterium. The bacteria grow by splitting its cells and this rate of division is regulated by temperature.

The Talstar® P label for mosquito control, however, says "not to apply to bearing fruit or nut trees or vegetables or edible crops.

A Systematic Review: Polyphenol Contents in Stressed-Olive Trees and Its Fruit Oil

For information about UMaine Extension programs and resources, visit extension. Find more of our publications and books at extension. Apple trees are important for wildlife in Maine and all the New England states. This region is fortunate to have many apple trees growing in the wild but, for a variety of reasons, a lot of these trees are being lost each year. This fact sheet describes a systematic way to restore and care for apple trees, to enable them to thrive and provide food and other habitat resources for wildlife. We include information on some of the many birds, mammals, and insects that use apple trees and the clearings around them. Apple trees and crabapple trees are in the genus Malus. Only four species of apple, all of them crabapples, are native to North America. No species occur naturally in Maine. Neither apples nor crabapples outcompete native vegetation for space, light and nutrients.

Disease and Insect Control for Homegrown Peaches and Plums

A sufficient intake of fruits can alleviate micronutrient deficiencies and reduces the risks of a number of associated diseases. In many parts of sub-Saharan Africa, however, the production and consumption of fruits are inadequate on average and in particular so in specific seasons. We here present this approach and illustrate it with data from a case study involving Western and Eastern Kenya. In our case study, 31 fruit tree species were reported on farms in our Western Kenya sample 9 of which were indigenous and 51 27 indigenous in Eastern Kenya.

A fruit tree is a plant that flowers and bears fruits. They are, however, susceptible to diseases when under stress. The antifungal chemicals applied to food crops and fruit trees include; dithiocarbamates, captan, and mercurials. While it is possible yet a problematic task to revive a dying sapling, it is impracticable to rescue a dead plant. Fungicides are harmful to humans if consumed in lethal doses. Due to their toxicity, they risk the environment when they are washed away by rain into the water systems.

When specifying fruit trees, variety and rootstock are the two most important factors.

Olive oil includes high amounts of phenols and polyphenols. Through health benefits to humans, the antioxidant role of polyphenols that contain more than two phenolic hydroxyl groups has been well proven. Of those polyphenols, oleuropein, hydroxytyrosol, catechin, chlorogenic acids, hesperidin, nobiletin, and isoflavones are major compounds. Along with the present study, 1 the uses and biological roles of polyphenols have not been limited to their physiological roles to human health; their physiological roles for plant and aromatic values for plant are also evaluated; 2 possible roles of major components in response to environmental stressors are discussed; 3 bibliometric analysis of studies concerned with polyphenols in olive fruit oil has been done to evaluate the research trends concerned with polyphenol in olive fruit oil, considering the main theme of the studies. The study is concluded with highlights, limitation, and future outlooks. Stress is a difficult concept to be described in biology. Briefly described in various forms, it is defined as the power potential that brings damage to living things.

Imidacloprid is a systemic insecticide that has been available for many years under different trade names and concentrations. Systemic insecticides are taken up by the roots or other parts of the plant and then move internally through the plant tissues and kill insects eating those tissues. In contrast, non-systemic insecticides remain on the plant surface and kill insects by contact or ingestion of treated foliage. Imidacloprid has been available to commercial growers for use on edible crops for over a decade.
