They became a go-to product for all plant operations due to their pest killing efficiency. Their use ranged from small home gardens to large agricultural fields. Due to their chemical structure, many of these cause significant damage to natural ecosystems. Take DDT for instance. This element, commonly used in pesticides, is now labeled as a dangerous carcinogen. Moreover, other synthetic pesticides are a threat to bee populations around the world.

How To Use Neem Oil – The Organic Solution To Pest & Disease Control!

Jump to navigation. While the organically accepted fungicides and insecticides individually do not offer the same degree of efficacy or longevity as their conventional counterparts, when used in concert with each other along with conservation of biological control agents and cultural practices to reduce inocula, it is possible to produce a high percentage of fruit free of insect damage and disease symptoms within organic certification restriction on allowable materials Berkett et.

Ideally, organic fruit production involves a whole systems approach not just a substitution of organically-acceptable pesticides for non organically-acceptable ones. Research is continuing in New England to examine the challenges and opportunities of organic apple production.

Information from this and other research will be incorporated into future extension publications. The following information is based on observations by researchers and Extension specialists in Vermont and New York. Kaolin clay Surround , when used properly, has proven an effective organic option to deter pear psylla on pears, and plum curculio and first generation codling moth damage on apples.

Later season use can suppress apple maggot damage and second generation codling moth, but when used past early July when apple maggot becomes a threat, the increased chance of a bothersome amount of Surround residue remaining on apples at harvest becomes a limitation.

Also, full season use of Surround has been associated with an increase in phytophagous mite populations. To be effective, Surround must be applied in dilute gallons water per acre minimum applications, and a complete base layer must be present prior to target insect activity in the orchard. Application to manage plum curculio should begin in late bloom to prevent colonizing of trees by migrating adults. Azadirachtin e. Aza-Direct, Neemix is derived from the seeds of the neem tree, Azadirachta indica , which is widely distributed throughout Asia and Africa.

Azadirachtin has been shown to have repellent, antifeedant, or growth-regulating insecticidal activity against a large number of insect species and some mites. It has also been reported to act as a repellent to nematodes.

Neem extracts have also been used in medicines, soap, toothpaste, and cosmetics. It shows some activity against leafminers, leafhoppers, mealybugs, aphids, caterpillars, tarnished plant bug and pear psylla, but repeated applications at short intervals are probably necessary for acceptable control of most pests.

It can be used up to and including the day of harvest and reentry is permitted within four hours following application. It is relatively nontoxic to beneficials, but toxic to fish, aquatic invertebrates, and bees exposed to direct treatment, although relatively non-toxic when dried. It is therefore categorized as having a moderate bee poisoning hazard.

Clarified Neem oil Trilogy is labeled for a wide range of pest control or suppression uses, including use as a fungicide, insecticide, and miticide.

Specific uses have not been well-studied for every labeled pest; rates suggested on the label also vary widely. Neem oils have been found to suppress European apple sawfly and may deter feeding or egg laying of other insect pests. Research on its use as a scab fungicide has shown that it is ineffective as stand-alone material. Because Trilogy is an oil-based material cautions against mixing with other pesticides incompatible with oil, such as sulfur, should be followed. Trilogy applications have been found to form a persistent film on fruit and foliage that may make removal of residues such as kaolin difficult at harvest or pack out.

This product is toxic to bees if exposed to direct treatment and is hazardous to fish and aquatic invertebrates. Bacillus thuringiensis e. It contains spores and crystalline endotoxin that must be ingested by larvae with high gut pH to provide control. It is effective against many fruit pests, including leafrollers and fruitworms. Although this material will contribute to the management of codling moth and other internal lepidopterous apple pests, it is not as effective as most conventional insecticides.

One exception is the obliquebanded leafroller, which has become so difficult to control with conventional toxicants that the Bt products work at least as well as any material available. Compared to conventional insecticides used against these pests, Bt insecticide coverage should begin earlier and requires shorter intervals between spray applications.

This material is exempt from requirements for tolerance on all raw agricultural commodities, thus it can be sprayed up until harvest. It is harmless to humans, animals, and beneficial insects, including the honey bee. Spinosad e. Entrust is an organically accepted formulation that can provide good control of codling moth, leafollers, and fair control of apple maggot and spotted tentiform leafminer.

Formulations with an attractant bait GF can be used at low rates to manage fruit flies. Pyrethrum e. Materials containing pyrethrins have been used against European apple sawfly and for short-term relative to conventional insecticides control of plum curculio, codling moth and apple maggot. Pyrethrins are rapidly broken down when exposed to UV-light and therefore applications in late evening are recommended. For the duration of control it provides, Pyganic would be more expensive than conventional insecticides or other organic options as the foundation for an insect pest management program.

AZERA controls insects through three modes of action: contact, ingestion and insect growth regulatory activity. It can be used to kill hard-to-kill insects such as Japanese beetles and stink bugs. This product is toxic to aquatic organisms, including fish and invertebrates and is highly toxic to bees exposed to direct treatment on blooming crops or weeds. Therefore, do not apply this product or allow it to drift to blooming crops or weeds while bees are foraging in the treatment area.

Insecticidal soaps e. They can provide suppression of pear psylla when used in a seasonal spray program, but the residual period is short, and uniform drying conditions are required to prevent droplet residues on the fruit surface. They have a low bee-poisoning hazard. Horticultural oil is an effective tool against mite pests, San Jose scale, and pear psylla, and can contribute to suppression of codling moth and spotted tentiform leafminer. Oils act as physical pesticides by creating a film over eggs, spores, or soft-bodied insects, thus suffocating them.

A dormant or prebloom oil application can help manage mite populations; additional summer oil applications can also lower populations. However, some apple varieties have different sensitivities to summer oil sprays and use may result in fruit and foliar damage.

Codling Moth Granulosis Virus e. These products contain an insecticidal baculovirus, Cydia pomonella granulovirus, which is specific to the larval form of the codling moth and is registered for use in apples, pears, and Cyd-X and Madex HP only plums. Madex HP is also registered for use against oriental fruit moth. This biological insecticide must be ingested in order to be effective. The virus infects the moth larvae and causes it to stop feeding and eventually die.

After death, the larva disintegrates, releasing the virus, which may infect other codling moth larvae upon ingestion. Applications are recommended at egg hatch, before the larvae penetrate the fruit. Best results are seen with repeated applications for each generation during the growing season.

No adverse effect to fish, wildlife or beneficial organisms has been observed; it has a low bee-poisoning hazard. Chromobacterium subtsugae Grandevo is a relatively new bioinsecticide registered for use against multiple insect pests on tree fruit.

Its mode of action is complex, and is generally effective when consumed by target insects. Grandevo may be used against codling moth and other lepidopteran pests and may be useful in rotation with other materials including granulosis virus or Bt to improve efficacy and manage development of pest resistance to those materials. Burkholderia rinojensis metabolites Venerate XC is labeled for control of pear psyllid and plum curculio and suppression of stink bugs on apple; as well as lepidoptera and plum curculio control and aphid, mealybug, mite, stink bug, thrips, and whitefly suppression on stone fruit.

Field research trials are lacking however for these uses of this product, so use beyond trial applications is not recommended. Synthetic pheromones are available for disrupting the chemical communication of certain insect pests, thereby preventing them from mating and producing larvae that injure the crop.

Pest-specific pheromones are released from dispensers or microcapsules placed in the orchard before the initiation of flight, and can reduce or in some cases eliminate the need for supplementary insecticidal sprays. This approach works best in large A or more , rectangular plantings, where the pheromone concentration in the air is more uniform and can be maintained at a high level.

Border insecticide sprays may be needed in orchards adjacent to sources of adult immigration or in other high pressure situations. Growers should contact their certifying agencies to determine which specific pheromone materials are acceptable in their state.

Fruit Tree Care: Spray & Weed Control

The apple maggot is a small fly native to the northeastern United States and Canada, where it originally fed on hawthorn. It was not until years after apples were introduced to North America that it was found feeding on apples, and today it is a key pest of apples in northeastern regions, where several insecticide sprays are necessary to produce fruit free from maggot injury and contamination. It has since migrated to the PNW, where it was originally found in Portland inBy it was found in most western Oregon and Washington counties. The apple maggot remains a potential threat to the commercial Northwest apple and pear industry in the Columbia Basin. The maggots develop in apples, quince and the fruits of native and ornamental hawthorn. The apple maggot also may occur incidentally in pear, plum, and tart cherry. Fortunately, the apple maggot seems to attack only apple and hawthorn in Oregon and Washington, and so far has not been found on pear. Early cultivars of apples are particularly susceptible to damage.

Providing adequate air circulation will help avoid powdery mildew in your garden. Powdery mildew is one of the most widespread and easily identifiable plant fungal diseases.

And that is particularly true for powdery mildew of apples and crabapples, Podosphaera leucotricha. The apple powdery mildew attacks both cultivated and wild apples and crabapples. And it occurs in the all regions of the world that produce apples! Powdery mildews get their name from the white spores that are produced by the mycelia fungal threads. The disease on apples attacks virtually every stage of the plant — buds, blossoms, new shoots, leaves, and fruit. We link to vendors to help you find relevant products.
