A little knowledge to share with you about what kind of pesticide is good for apple flowers, let's find out together.
What kind of pesticide is good for apples
If apples want to grow fast and yield high, it is related to the spacing of fruit trees, climate, and maintenance, etc. In planting, we should adhere to the use of biological and non-harmful pesticides, and strengthen drug protection from 3-5 days after the flowers fade to before the fruit bagging to prevent the fruit from being infected by pathogens. In the early stage of fruit infection, it is necessary to spray the fruit trees with pesticide synergists and other substances. When using pesticides on apple trees, one cannot arbitrarily increase the amount and scope of pesticide use, and attention should also be paid to the appropriate time, safety interval, and safety withdrawal period for pesticide use.
Apple spraying
Yield: The yield of apples is related to the spacing of fruit trees, climate, and maintenance. If the fruit yield is low, it can generally produce about 2,000 jin, while medium yields can produce 4,000 jin, and high yields can produce about 6,000 jin.
In apple planting, we should adhere to the use of biological and non-harmful pesticides, as well as new fungicides, to produce high-quality apples.
Apple pesticide application time
From 3-5 days after the flowers fade to before the fruit bagging, the fruit should be strengthened with drug protection to prevent the fruit from being infected by pathogens, and the fruit trees should be sprayed with pesticides before rainfall.
Apple pest and disease control chemicals
1. Disease control:
Common diseases of apples include leaf blight, (T-J) disease, and heart rot disease. In the early stage of fruit infection, a 15% wettable powder of myclobutanil 1000 times liquid and organic silicon pesticide synergists can be used to spray the fruit trees.
2. Pest control:
Common pests of apples include red and white spiders, scale insects, and aphids. You can use multi-effect spirit (tetramine copper) 150 times, add 100 times urea, and then add 40% chlorpyrifos 700 times for spraying.
3. Pesticide use taboos:
When using pesticides on apple trees, one cannot arbitrarily increase the amount and scope of pesticide use and should also pay attention to the appropriate time, safety interval, and safety withdrawal period for pesticide use.
The above is a detailed introduction to what kind of pesticide is good for apples. Do you understand now?
