Spraying fruit trees is often a very easy thing to do, as long as you know when to do it and what schedule to keep. As with many types of trees, fruit trees can suffer from a variety of ailments, some relating to fungus and others relating to insects. In most cases, finding a fruit tree spray that will take care of both problems is the most advantageous, but this can also be an inconvenience during certain times of the year. Doing this requires adhering to strict guidelines regarding when to spray and when not to spray.
Spraying Fruit Trees
Wait until trees begin budding in the springtime. Most fungus and many insects will not become active to this time of the year, simply because the temperature prevents such infections or infestations prior to this time.
Use a fungicide, and possibly an insecticide, when green vegetation is first seen on the tree. The springtime is often a very cool and wet period, which can lead to the growth of fungus. It is always more effective to treat the trees before fungus becomes entrenched and begins to spread to other portions of the trees.
Spray insecticides and fungicides enough to coat as much of the vegetation as possible. Many people use pump sprayers to accomplish this. This should be done both on infected leaves, if any, and those that are apparently healthy.
Do not spray insecticides while flowers are blooming on the fruit tree. This could kill bees and other insects that are used to pollinate the trees. Therefore, spraying with an insecticide could be counterproductive when it comes time to actually harvest the fruits of your labor.
Begin spraying insecticide, along with fungicide, after flower petals have dropped. Continue this spraying every two weeks until harvest time, or as needed. Generally, try to wait at least two weeks between applications.
Stop spraying insecticide after harvest or the first hard freeze. At this point, the leaves will begin to fall off the tree and any insects and fungus should be killed or going dormant, making spraying minimally effective.
Things You Will Need
- A combination spray, consisting of both fungicide and pesticide, can be used in most cases.
- Some pesticides can be applied before vegetation appears in the spring, especially if you know there is already a problem.
- Never use a combination during flower blooms.
- Be careful to keep fungicide and pesticide chemicals out of the reach of young children.
