A great deal of research has been done on the life cycle and vulnerable times for most pests, he said. As a result, less spraying is necessary because specific periods can be targeted when pests are active and more susceptible. Better, safer products are now available on the market, and many of them are classified as botanical, which means they are not synthetic-based. This fungal disease thrives under such conditions, so it could cause problems again this year.

As leaves tumble to reveal bare branches, nights become longer and frosts fiercer, it can be tempting to believe that pests are no longer on the prowl. But late fall and early winter is a crucial time of year for preventative pest control on fruit trees.

There are five simple techniques that I have found to be effective at keeping fruit tree pests at bay.

Conveniently, they can be carried out once the frantic pace of the main growing season has passed, meaning you can give your full attention to this important task. Not all moths fly, which is why glue bands and tree barrier glues are very effective measures against destructive caterpillars.

The caterpillars of winter moth are often the culprit behind holey leaves on plums, apples and other trees in spring. They will also damage developing fruits, so that they either drop while still immature, or grow misshapen, scarred and sometimes holed. Adult winter moths lurk in the soil until late autumn, when they emerge to mate. Once mated, the wingless female clambers up a tree trunk and lays her eggs in the branches. She can be stopped in her tracks by a sticky barrier. Glue bands work well on trees with smooth bark like my plum tree in the photo at the top of the page.

Trees with more fissured bark can be protected by slathering on tree barrier glue directly. Aphids are regular visitors to my apple trees every autumn, congregating on the leaves before they fall and laying their eggs in the branches. Aphids feed on new shoots of fruit trees and can cause leaves to become disorted. In severe cases, fruiting may be affected. Minor infestations, particularly on larger trees, are unlikely to cause major problems and can often be ignored.

On younger trees, if aphids have been a problem in previous years, it may be necessary to take action. The first step is to use a jet of water to dislodge aphid eggs. It will destroy aphid eggs and other overwintering pests. For it to be effective, a winter wash needs to be applied in early winter, after the leaves have dropped, and again in spring before the trees burst into growth. Choose a windless, dry day to apply winter wash, and wear gloves and goggles.

Believe me, blowback is not pleasant! Dilute the concentrated winter wash with water in a spray bottle and give the bottle a shake to mix it well. Spray it onto your trees, paying special attention to any nooks and crannies where branches join, and around the buds. I find that using a soft brush to gently scrub particularly badly infested areas helps. Spray any tree stakes too. Some pests will overwinter in leaf litter or in the soil around your fruit trees so they can be near to their food source when spring comes around.

Good garden hygiene is the answer. Rake up all fallen leaves and compost them away from your trees to foil pests such as apple blossom weevil, which can destroy flowers and ruin your fruit crop. If your trees are surrounded by soil rather than grass, rake around them to expose overwintering pupae of bugs such as sawfly to frost and birds. Tree bark is often nibbled by hungry rabbits, voles and other rodents. Using a tree guard prevents stripping of the bark.

Plastic tree guards are not, in my opinion, the best choice; I have found that they can harbor pests and they tend to keep the bark damp, which encourages disease. I prefer to make a protective tube of wire mesh, as it allows free flow of air, is less hospitable to insect pests and is impossible for rodents to gnaw through. Flex the mesh into a tube and secure it using cable ties or wire. Use a cane to keep the tree guard upright, and make sure the wire is pushed firmly into the soil with no gaps at ground level.

You may be able to remove guards in summer if the rodent problem is limited to the winter months. The larvae of lacewings, ladybeetles and hoverflies are voracious pest-munchers.

Weather permitting, the period between autumn and spring is a good time to establish more nectar-rich perennial flowers to attract these and other pest predators. Try bugle Ajuga reptans , asters, daisies or lavender for starters. Make sure to provide overwintering habitats so that predators are on hand to step in when pests begin to become a nuisance next year — piles of stones or twigs, hedges and hollow standing plant stems all make great habitats, or you can make a bug hotel.

While birds often get a bad reputation for snacking on fruit, insectivorous birds are excellent pest controllers. Get their attention by providing habitat, winter food and water, and they will seek out bugs in your trees and in your soil. Protect Against Winter Moth Using Glue Bands Not all moths fly, which is why glue bands and tree barrier glues are very effective measures against destructive caterpillars.

Caterpillar damage can be avoided by using glue bands Adult winter moths lurk in the soil until late autumn, when they emerge to mate.

Expose Overwintering Insect Pests Some pests will overwinter in leaf litter or in the soil around your fruit trees so they can be near to their food source when spring comes around. Prevent Ring-barking by Rabbits and Other Rodents Tree bark is often nibbled by hungry rabbits, voles and other rodents.

Encourage Pest Predators The larvae of lacewings, ladybeetles and hoverflies are voracious pest-munchers.

A properly executed schedule for maintaining fruit trees and their growing site is key to success. Plan ahead: the rewards are worth the effort! Summer is finally upon us , and it's time to take a good look at our fruit trees. Pest and disease control — in the form of a well-maintained growing site, as well as sprays either natural or synthetic — are things to practice on a year-round basis. Keeping a growing site clear of debris and weeds will help keep down the risk of fungal infections and environments suitable for pests.

Apple is one of the most widely cultivated fruit trees in the temperate climates of the pesticide sprays to provide supplemental control.

Fruit Tree Care: Spray & Weed Control

Helen told me several years ago that she grows tomatoes in the summer and has four fruit trees, including a satsuma plum, an espaliered apple and a tangerine. Helen battles peach leaf curl on her plum and codling moth larvae inside her apples and would like to know exactly what to use and when to control these problems. You can prevent or control many diseases and overwintering insects by applying a dormant spray this month. This can be the most effective spray of the season. Fungal diseases such as peach leaf curl, fire blight, scab and anthracnose as well as insects including aphids, San Jose scale, bud moth, leaf roller, whitefly larvae, mealybugs and mites can all be controlled by dormant spray and horticultural oil. There are several types of dormant sprays and all three types are considered organic. Lime-sulfur or copper can be mixed with horticultural oil which smothers overwintering insects and eggs. This spray is good for all fruit trees except apricots which should be sprayed in the fall with copper and this month only with horticultural oil. Apply dormant spray when the temperature is above 40 degrees.

5 Organic Ways to Foil Fruit Tree Pests

Pest Control. It is hard to beat the enjoyment of biting into a fresh, delicious, pest free delicious peach! The image of the Okanagan region is memorialized for its apples, peaches and tree fruits. More recently, it has become renowned for its wines, ciders and organic produce. Noxious pests are insects or related pests that are capable of devastating fruit bearing trees and shrubs in both residential and commercial plantings. Noxious Pests often lack natural enemies and can quickly take over plantings from single fruit tree in a backyard to an entire commercial orchard.

Fruit & Tree Spray

Apple and pear trees are subject to serious damage from pests. As a result, a preventive spray program is needed. The following practices will improve the effectiveness of the pesticides and may lessen the need for sprays. Peach, plum, and other stone fruits are commonly affected each year by several insect and disease problems. A spray program is therefore needed for successful fruit production.

The first Group 23 insecticide registered in Australia, Movento Spray coverage and overall tree health are important. Poor spray coverage and/or any.

Prevention is the first step in controlling diseases and insect pests in home orchards.

Kaolin Clay Sprays for Fruit Trees

Kaolin clay sprays are an important organic orchard strategy used after petal fall to repel many types of pest insects and protect trees from sunburn and high temperatures. Kaolin clay repels pests by making the fruit tree an unsuitable environment for certain insects to land, feed and lay eggs. The tiny clay particles serve to disguise the target fruit and can clog the eyes, ears and reproductive organs of many common pest insects including apple maggot, plum curculio, codling moth, european apple sawfly, oriental fruit moth, tufted apple bud moth, white apple leafhopper, and pear psylla. It is important to build up a proper covering of clay on your trees or it will not be effective. Spraying at least 3 times, each application a week apart, after initial petal fall is recommended. A sprayed tree will be coated my a thin white film of clay particles.
