Pesticide phytotoxicity checklist

Hello, come to consult our products !
Propiconazole

Use in the seedling stage is easy to reduce the seedling rate, seedling rigidity, inhibit growth, burn young fruit, try to use it in the middle and late crops;
 it is sensitive to melons, grapes, strawberries, tobacco and other crops.

Pentachloronitrobenzene

Pentachloronitrobenzene is prone to phytotoxicity when it comes in contact with the sprouts of crops

Chlorothalonil

The high concentration of chlorothalonil is prone to phytotoxicity to pear trees, persimmons, peaches and plums. The apple cannot be used within 20
 days after the flower has fallen.

Hymexazol

Can not be mixed with strong acid medicaments, 100 times liquid has slight phytotoxicity to wheat.

Kasugamycin

It has slight phytotoxicity to soybeans and lotus roots, and it cannot be used in neighboring soybeans and lotus roots.

Engine oil emulsion

Spray oil emulsion 150 times + 40% hydrocarbophos 1200-1500 times during the germination and florescence period, causing phytotoxicity;

organophosphorus pesticides should not be used within 1 week after spraying loose alkali mixture, and lime-sulfur mixture should not be sprayed within 20 days

copper chloride

The young leaves of crops such as apples, grapes, soybeans, and lotus roots are sensitive to the drug and will appear slightly curled and brown spots.

Bordeaux mixture

Cabbage, peach, and plum are sensitive to them during the growth period, and no matter what the formula is, they are prone to phytotoxicity. In spring, it can
 prevent citrus scab disease. The temperature exceeds 30℃ and the bud length exceeds 1cm. Spraying 0.8% equivalent Bordeaux mixture will produce For 
severe bud burning, it is safer to spray 0.5% double-volume Bordeaux liquid; pears are sensitive to copper ions, use double-volume Bordeaux liquid; grapes
 are sensitive to lime, use lime half-volume Bordeaux liquid, such as the high temperature period around noon in summer , Overcast and rainy days, wet fog
 in the morning, and strong wind spraying are all likely to cause phytotoxicity。
