Fruit tree remedies

In the process of fruit tree growth, due to the spraying of liquid pesticides, powder pesticides, or misuse of pesticides, the growth of fruit trees has an adverse effect. This is what we call phytotoxicity. The production of phytotoxicity of fruit trees is related to the nature of the drug itself, the type of fruit tree, the growth and development period, the physiological state and the environmental conditions after application. In the event of phytotoxicity, if remedial measures are not taken immediately, the lighter will affect the normal growth of the fruit trees, resulting in reduced production and reduced income; severe cases will lead to the death of fruit trees, causing serious losses. The following are some of the remedies for fruit tree phytotoxicity.
First, watering and spraying. If found early, the affected plants should be sprayed with water immediately to dilute and wash off the pesticides adhering to the foliage and branches, and reduce the pesticide content in the trees. The sooner the measure is taken, the better the effect will be. If it is a phytotoxicity caused by a systemic agent such as volcanic granules, it is necessary to take measures for irrigating and irrigating in a timely manner, that is, first flooding the orchard surface, then 1-2 times of horse water to wash away the soil. Residual pesticides.
Second, timely fertilizer. After the fruit tree suffers from phytotoxicity, its growth is hindered and its growth is weak. It must be topdressed in time (nitrogen, phosphorus, potassium and other chemical fertilizers or thin human excrement) to promote the recovery of the affected fruit trees as soon as possible. If the phytotoxicity is caused by acidic pesticides, some ash or quicklime may be applied, and 1% of the bleaching powder may be applied to the foliar spray. Phytotoxicity caused by alkaline pesticides, topdressing acidic ammonium sulfate fertilizer. Whatever injury, spraying the urea solution plus 0.3% 0.2% potassium dihydrogen phosphate mixed solution, once every two weeks, 2-3 times even spray, and can reduce injury.
Third, the injection water. When prevention beetles, Gidding insects, moths and other wood sac Boring Beetle, injury due to high drug concentration caused immediate worm hole from the trunk of the tree plenty of water injected into the body, and make it out of water to dilute the pesticide. If it is an acidic pesticide, adding an appropriate amount of quicklime to the water injection solution can accelerate the decomposition of the pesticide.
