Insecticide Options in Organic Apple Production

Peaches represent the largest increase in organic fruit acreage in the United States Perez and Plattner,California, Washington, and Oregon currently supply the majority of domestic organic fresh market peaches Hallberg,Data from organic peach producers in the southeastern United States is largely unavailable due to USDA Agricultural Census reporting privacy policies and low production, but South Carolina and Georgia rank as the second and third largest conventional and organic peach-producing states behind California USDA National Agricultural Statistics Service,Nationwide, producers select peach varieties based on chill requirements that range from less than to over 1, hours and full-bloom dates that occur after the last potential freeze.

In the Southeast, peach producers harvest fruit up to two months before West Coast producers, and meet market demands from April through September. Organic peach production in the Southeast has been difficult due to the prevalence of insect and disease pests, as well as the lack of effective organically-approved pesticides Horton et al, ; Blaauw et al. In addition, many of the compliant, commercially-available pesticides contain copper and other ingredients that may negatively impact soil health with overuse USDA National Organic Standards Board,Pests and diseases can affect fruit quality throughout the entire growing season and at postharvest.

For example, the insect pests green stinkbug Chinavia halaris feed, and plum curculio Conotrachelus nenuphar oviposit in fruit during initial growth development. Bacterial spot Xanthomonas arboricola and peach scab Cladosporium carpophilum cause unmarketable skin blemishes and spread when the humidity and temperature are optimum for growth. The most prevalent end-of-season and postharvest fungal diseases include brown rot Monilinia fructicola and rhizopus Rhizopus nigricans.

Organic fruit producers in the United States, Spain, Japan, and China have been installing paper bags on fruitlets to provide a physical barrier from both pests and pathogens Sharma et al. Research has shown that bagged fruit, as compared to a non-bagged control, can increase fruit quality and yield for a variety of crop-pest complexes Table 1 , but have shown mixed results for other characteristics Table 2.

Based on these results, researchers in the southeastern United States are currently evaluating bagging as a potential pest and disease management technique. Melgar and G.

Schnabel publication forthcoming demonstrated that bagging peaches increased the amount of marketable peaches in an organic orchard, and customers were willing to pay more for bagged peach fruit.

Furthermore, preliminary calculations indicate that grower costs may increase around 10 to 15 cents per pound produced to cover the extra bagging cost Hallberg,Table 1. Insects and diseases that are controlled by bagging in conventional operations.

Peach, Guava, and Mango.After the last potential frost event, flowers and fruitlets are removed, also referred to as thinned, to lower the fruit-to-leaf shoot ratio and promote larger sized fruits Costa and Vizzotto,The bagging practice under current investigation is conducted after thinning and includes one or more applications of organic-approved pesticides to reduce insect damage and pathogen growth on fruitlets prior to bagging.

Currently, bagging Video 1 is recommended within three days of an organic-approved pesticide application, or as early as the re-entry period starts, to maintain a lower pathogen count on the fruitlet surface. On-farm bagging research trials with certified USDA organic or transitioning organic farmers in South Carolina, Georgia, and Florida were initiated in , but only the Florida location is discussed below. In Florida, fruits were bagged 35 days after full bloom with a white paper bag impregnated with water-resistant wax Fig.

After identifying the fruitlet Fig. At this time, the fruitlet should be completely enclosed in the bag, the branch should be snug with the notch, and the bag should extend past the fruiting branch. Next, the portion of the bag that is extending on the opposite side of the branch as the fruitlet is cinched in an accordion-like fashion and secured by a twist tie that is part of the bag.

Next, the twist tie is rotated at least degrees around the cinched paper and the secured bag should not rotate around the branch when slightly agitated Fig. The bag will remain on the branch for the duration of the growing season and removed or ripped open to increase light penetration and promote blush development Kataoka and Beppu, at the end of the season.

Depending on the bag material, the bags can be recycled after removing the twist tie. Video 1: Peach Bagging. Video credit: David Campbell, University of Florida. Figure 2. Size of fruit relative to fruit bag. Photo credit: David Campbell, University of Florida. Figure 3.Fruit bag properly installed. The experiment was arranged in a randomized block design that tested two factors—bagging all fruit were bagged on a tree or not bagged and tree ordinance north, south, east, and west quadrants of the canopy.

Twenty-four trees were divided into four replications based on trunk diameter. During the growing season, insect traps were installed, tree phenology was assessed, and disease assessments were conducted. Postharvest evaluations included fruit size, weight, insect damage, and postharvest rot progression. Postharvest data were analyzed using the glimmix procedure in SAS version 9. The ordinance factor and all interactions were not significant. The experiment will be repeated and additional quality characteristics will be evaluated.

Top 10 Organic Pest Controls

Commercial fruit growers are all too aware of the problem pest birds can do to their crops. You might think everyone would implement pest control methods, but many will take the potential losses and incur the cost as part of their fruit production. This method prevents the birds from getting to the fruit. However, it can be expensive and very labour intensive to install and maintain. Good old-fashioned scarecrows or the latest designs that have infrared sensors that detect the birds and squirts a jet of water to startle them.Natural predators are becoming widely used in large commercial orchards. Placing owl nesting boxes and encouraging a natural environment for predators to live is being used an effective way to control pest birds.

Welcome Birds to Your Garden. One of the best ways to naturally control your insect population is by inviting feathered friends to take up.

When To Spray Apple Trees

Spraying your apple trees is all about timing. When you are prepared with a spraying plan and ready for action, you can keep you home orchard free of pests and diseases. You will enjoy a bumper crop and harvesting will be a pleasure. Traditional non-organic insect pests and disease control uses toxic chemicals to keep fruits pretty and marketable. Organic measures of insect pests and disease control may require a more hands-on approach, however the outcome is healthier fruits that may not be pretty and shiny. Garden centers are carrying more organic pesticides, fungicides, and herbicides than ever before. It is much easier to keep our gardens pest free and stay organic too. It is always a good idea to avoid any type of spraying while the flowers are open. During the blossom stage, your plants are in the pollination process and spraying can adversely affect bees and other pollinators. Dormant Sprays or dormant oils are a horticultural oil sprayed on the tree trunk and limbs during your apple trees dormant cycle.

Organic treatments for your fruit trees

The integrated pest management IPM approach to preventing and managing pest problems is highly recommended and can be summarized as follows:. Scout plants regularly and thoroughly. Correctly identify the cause es of observed problems and learn more about them. Learn to anticipate and prevent problems.

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.

One way of reducing pest damage therefore is to create an orchard habitat that encourages biodiversity and these natural enemies. Many pesticides will kill these beneficial species as well as the pests you are trying to control, which means your first line of defence is removed or weakened the next time the pest species attacks your fruit trees or crop.

Fungicides protect the plant or fruit from infection; they do not eliminate the Partially rotted peaches lie on the ground underneath peach trees.

No matter how good a gardener you are, at some point or another animals, insects, and diseases will attack your plants. Organic gardeners know this is a fact of nature and will tolerate some damage to their fruit trees, berry bushes, vegetables, and herbs. A perfect plant doesn't mean one that is completely blemish-free. However, if left unchecked, a little damage can quickly turn into a lost crop.

What are a couple products you recommend a backyard grower have on their shelf that will help manage most issues in NH and Maine? So good record keeping and planning will help.

This fact sheet is designed to reflect the changing attitudes of most growers who produce fruit in neighborhood settings. Concerns about pesticide residues, drift, toxicity, and application methods may dictate how and when chemicals are used. Pesticide spray schedules are normally developed for worst-case scenarios, and large-scale production under severe pest pressure. Production of fruit for personal consumption allows the homeowner grower to decide how much cosmetic damage he or she is willing to accept. With the proper selection of well adapted varieties that have good resistance to insect and disease problems, application of pesticides may be reduced or modified to provide adequate control of pest numbers while preserving beneficial organisms.

Apples are pollinated by insects, with bees and flies transferring pollen from flowers of one apple tree to those of another. But you don't need to plant a whole orchard to enjoy apples right off the tree. Two trees will reward any family with enough fruit to enjoy and share with friends. Apples require pollen from a different apple variety to grow fruit.
