Injections for fruit trees for eating leaves
1. For apples, pears and peaches
There are lots of options for getting in organic fertilizers and pesticides for fruit trees.
Organic options range from deep organic root supplements that are vacuum applied, to organic fertilizer such as fish emulsion, manure compost and wood ash.
You can also use chemical pesticides that have been registered for use on fruit trees and other plants.
Organic options are more expensive and often more challenging to apply than their chemical counterparts.
Start by finding the right organic fertilizer or pesticide for your fruit trees. It is best to apply a low rate of fertilizer or pesticide.
An important tip is to apply a product like one of the standard synthetic pesticides used for apple trees.
Apply before fruit is expected and during dormancy to protect against problems with fruit dropping in late season.
Using a standard spray will reduce your risk of having fruit pest problems the following year and reduce any chance of your fruit being damaged by pesticide.
Often, products like fipronil can be used on apple trees. Other chemical options include metamidophos (a phosphorothionate insecticide), oxamyl (a carbamate insecticide) or cymoxanil (an imidazole fungicide).
Be careful when you apply pesticides to a tree. Wear thick gloves and a respirator, and be careful not to spray close to where you will be working.
Never spray or use products close to water sources.
If you have an issue with insects, take a sample of the infected fruit and take it to a local lab for identification and treatment options.
Many businesses that make testing available will offer a free identification and treatment consultation.
If you have no other options, try washing and stripping infected fruit off the tree and placing the fruit in an organic or natural food storage container in a cool, dark place.
Make sure the fruit is completely removed by cutting down on it if it is stuck in fruit.
Bareroot trees that can be planted should not be allowed to be stored for more than two weeks before being planted.
If it has been longer than this, bring them in when it is safe to take them from storage.
Do not bring in any trees before spring or after late fall.
Apple leaf pullers are fun to watch but they are more often associated with failure than success.
In most cases, a fungicide called "Fusaric Acid" is the main ingredient and that fungus is transferred from the leaf to the fruit when it becomes ripe.
Sulfur was historically used to prevent this.
Bacterial wilt of pears is caused by bacteria and it will often occur if a tree is not fertilized.
It may also occur if a nearby apple tree has a fungus such as apple scab, for example, that is introduced into the soil.
In many cases, you can control these diseases by getting a good organic fertilizer for your pear and apple trees.
Roots should be supplied with a deeper fertilizer.
A small amount of fertilizer will help keep roots healthy and productive.
Use products such as compost, manure or fish emulsion to get the job done.
Most importantly, be sure you are applying a foliar spray at a time when trees are actively growing, for example, late in the growing season.
Fruit trees have a short season.
If you wait until late in the season, you run the risk of a low level of fungicide or other product in the soil or on the roots being transmitted into the fruit.
If the fruit is badly infected, there is a risk of the fruit falling, a result of low levels of fruit caused by the infection in the fruit.
Some methods can help keep bacteria from invading fruit trees from ground around the tree.
A possible way to help prevent a problem in the first place is to spray nearby apple and pear trees with a substance called a trifluralin.
It has to be applied about a month before harvest, and the research shows that it works.
It can be applied with a normal broad-leaf sprayer as a contact fungicide to the area surrounding fruit trees.
Trifluralin has been shown to work against bacterial wilt in pears and bacterial canker in apples.
Once again, the advantage is that you can spray during a short time and you won't waste time trying to prevent the infection from moving into the fruit.
Perhaps a preventive treatment before the disease appears, such as an application of dazomet, the other active ingredient, might work as well.
We have all experienced when we wanted to get a tree and it was late, the nursery was closed and our selections were slim.
If we wanted a variety of apples, pears, plums or peaches, we were limited to what we saw in our immediate surroundings.
Well, most of the time, that means what is in the organic and chemical section of the nursery.
Now, I am not suggesting we are limited to those products or what is available.
The suggestion is that we ask
