Apple tree pests, diseases and problems

A: Caring for fruit trees is a year-round job that includes pruning, fertilizing, removing diseased fruit, and spraying at different times of the year. Timing is critical for each of these tasks. During active growth, the trees absorb and use nutrients from fertilizers. To know when to spray fruit trees for pests, you first need to know what threatens the tree and when the threat is active. An insect egg can lie dormant in the bark of an apple tree all winter, only to hatch and feed on the leaves in spring.

Or a particular fungal spore might infect a peach tree only while the flowers are open. Time tree spraying applications to control diseases and insects. Timing coincides with plant and fruit development, along with climate and weather. Watch for specific growth stages with observable characteristics:. Avoid spraying fruit trees while flowers are open, since insecticides sprayed at that time kill bees and other pollinators. Read and follow all safety precautions to minimize personal exposure to pesticides.

Always follow mixing instructions. Increasing the concentration of a spray does not kill insects faster, can kill more beneficial species, and increases chances of runoff contaminating local streams and groundwater.

Dormant sprays kill overwintering insect pests on fruit trees. Unless pest populations spike, it is not necessary to spray dormant oil every year. Every 3 to 5 years is typical. Complete dormant spraying before buds begin to swell. Apply dormant spray only when the temperature is above 40 degrees Fahrenheit. Be sure to fully coat all surfaces, paying close attention to undersides of branches and branch crotches.

It is possible for insects to build up tolerance to even the best insecticide if it is used repeatedly. The solution is to alternate applying insecticides with other active ingredients. If you primarily use a general-purpose spray to kill insects and diseases, alternate treatments using a specific-purpose insecticide to eliminate the risk of pests building up tolerance to either chemical.

An insecticidal soap such as Natria Insecticidal Soap can be used right up to the day of harvest. Targeted, stand-alone fungicide treatments improve fruit quality when applied at the proper time. Fruit disease spores infect their hosts when environmental conditions are ideal.

Some fungal spores activate during cool, wet spring weather. Other diseases spread in hot, humid summer conditions. It is important to anticipate plant diseases and begin treating them just before they arrive. Fungicide applications are most critical during the green tip through petal fall stages of apple and pear trees. Peach trees and plum trees require spring, summer, and fall disease control treatments for best results.

Find application timing on the product label to prevent specific diseases or check this Purdue University Extension Guide for growth stage and fruit tree spray schedules specific to common fruits. Apply the spray first at green tip, followed by pre-bloom, full pink, petal fall, first cover 1 week after petal fall , and second cover 2 weeks after petal fall. General-purpose fruit tree sprays cut spray application time in half. A powerful mix of broad-spectrum insecticide and fungicide is the key.

Active ingredients might include organic products like pyrethrins and neem oil, or inorganic chemicals like malathion, carbaryl, and captan. If your fruit trees are deficient in zinc, copper, magnesium, molybdenum, boron, or calcium, a foliar application of one or more of these micronutrients may help. Be cautious; unnecessary or excessive application of these nutrients can damage fruit trees. Foliar fertilizer cannot replace proper soil fertility. A tree cannot absorb enough of the major nutrients it needs through foliage.

The best time to fertilize fruit trees is in early spring. The first flush of growth in spring comes from energy stored in the roots.By the time the fertilizer penetrates the soil, the tree is ready to take up the nutrients for optimum growth and fruiting. Avoid fertilizing after mid-spring. A spike in soil nutrients during fruit development can cause trees to abort fruit to produce more vegetative growth. Combination sprays are two different pesticides sold individually, normally an insecticide and a fungicide, mixed into the same sprayer and applied at the same time.

This practice is a way to customize an application and save time. Not all products are compatible, and some mixtures can be dangerous. Read both product labels before mixing to ensure that mixing the two is safe and allowable. Disclosure: BobVila. You agree that BobVila.

Fall Nutrient Sprays in Tree Fruit

Prevention is the first step in controlling diseases and insect pests in home orchards. Many problems can be avoided by choosing resistant fruit tree varieties and providing them with proper care. That care includes removing all dropped fruit and leaves that might be harboring pests. But even the most vigilant gardeners may need to spray their trees during the dormant season to reduce over-wintering pest and disease organisms. Spraying fruit trees during the cool seasons, November through March, can help control pests that take up residence in the cracks and crevices, according to Ross Penhallegon, horticulturist with the Oregon State University Extension Service. Such dormant spraying is more effective than waiting until the weather warms and pests become active. Below are some least toxic sprays and treatments for fruit trees.

The first spray of the season is a crucial for a healthy fruit tree. It's important to spray thoroughly the entire tree. Winter Pruning: New Fruit Trees.

Your Healthy Fruit Tree Game Plan + Copper Sprays Explained

Currently, growers are harvesting lettuce, broccoli, cabbage and other winter vegetable crops, and not thinking about spraying fruit trees and berry bushes for insects and diseases. February is prime time to apply dormant sprays to aid in the prevention of insect and disease issues later. In fact, the recent warm weather has triggered fruit trees to begin blooming, so if growers intend to apply dormant sprays, they must do so soon. Dormant sprays are applied to control insect and disease pathogens during the winter season. Many insects overwinter on trees and shrubs, either as eggs or immobilized in a protective shell scale insects. Horticultural oils, Sulfur and Copper all control different insects and pathogens, but can be applied during winter dormancy. Horticultural oils work by smothering the eggs of some insect species or encapsulated scale insects. Since they cannot breathe, they die. Sulfur compounds kill dormant or latent disease spores, and copper compounds kill bacterial cells that cause canker or fire blight.

Dormant Sprays for Fruit Trees

The first thing that comes to mind when thinking of autumn is surely the splendid bounty of nature; from magnificent autumn colour of the foliage to abundant harvests of fruits. With the right fruit tree care methods, you can always expect a bumper harvest.

In addition, an application of horticultural oil can further reduce overwintering pest populations. This article will focus on the use of horticultural oils to promote fruit tree health by reducing overwintering pests. The use of oils to control pests goes back over 1, years.

Applying Pesticide on Fruit Tree Pests

Depending on your location, significant rainfall has occurred recently in Pennsylvania. Unfortunately, these rainy, humid conditions are quite favorable for rot, both in establishment and spread.Vigilance is needed in the orchard, especially if brown rot pops up. Some nuggets of wisdom to keep in mind:. Brown rot disease is favored by warm, wet weather conditions.

The first year you should concentrate solely on complete removal of any main branches that are identified as diseased or badly damaged.

Fruit Tree Care: Spray & Weed Control

A three-pronged program of dormant oil sprays in fall and winter help keep fruit trees healthy. If you don't, chances are they'll struggle in the coming season. Giving them attention now helps ward off insects and diseases, said Steve Renquist, a horticulturist for Oregon State University Extension Service who has taught hundreds of gardeners the basics of managing fruit trees. Applying dormant sprays - Superior oil, copper, and sulfur - helps control nasty pests and diseases like codling moths and apple scab.

Different varieties of fruit trees are susceptible to different diseases.

Learning Center. Dormant oil refers more to when the oil has traditionally been applied rather than what it is made of. Newer dormant oil formulations are typically refined from petroleum oil, such as mineral oil. Unlike home remedies, they also contain an emulsifier to help water mix with the oil, which will provide more complete coverage of plant surfaces. Dormant oil may also be labeled as horticultural, superior or all-seasons oil; keep reading for more on this. The oil covers leaf and limb surfaces, suffocating insects and some insect eggs, which reduces harmful insect populations.

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.
