Matters needing attention when using several common pesticides, such as dichlorvos, trichlorfon, paracetamol, etc.

Pesticides refer to the chemicals used in agriculture to control diseases and insect pests and regulate plant growth. Improper use of pesticides not only can not assist delivery, but also may make crops die and endanger human health. The following is to introduce the dichlorvos, trichlorfon, chlorpromazine and other common pesticides when using points for attention! The broad masses of farmers may have taken a closer look.

1. Omethoate: some varieties of hops, Compositae, sorghum and tobacco, jujube, peach, plum, apricot, plum, olive, fig, citrus and other crops are sensitive to dimethoate EC with a multiple of less than 1500 times of water. Omethoate is prohibited on fruit trees.

2. Trichlorfon: particularly sensitive to corn, apple, sorghum and beans, easy to cause drug damage, peach trees are prohibited.

3. Dichlorvos: it is sensitive to sorghum, beans, rose, corn, melon seedlings and rubber, so you should use it with caution. It is very easy to cause drug damage to drupe fruit trees and should be prohibited. (if peach trees spray dichlorvos, trichlorfon, dimethoate, etc., before the hard core period, it is easy to cause fruit drop).

4. Clenbuterol: do not come into direct contact with cabbage and radish, otherwise there will be brown spots and green leaf albinism.

5. Chlorpyrifos: it is harmful to melon seedlings and should be used after the melon vine is 1 meter long; sensitive to tobacco.

6. Quick culling: avoid florescence use, so as not to cause drug damage. If the concentration increases at will, it will cause brown leaf spots. From June to July, when the temperature is over 30 ℃, the young fruit is easy to cause drug damage when the temperature is more than 80-1000 times.

7. Phoxim: sensitive to cucumbers, beans, taro, sugar beet, rice, corn and so on.

8. Diclofenac and triclofenac: sensitive to some apples and pears, the temperature is low and the humid weather is more serious. Triclofenac is forbidden to be used in tea and fruit.

9. Tricyclic tin: citrus is prone to drug damage.

10. Triazoltin: spraying triazotin 1500 times from August to September will increase the incidence of orange fruit sunburn.

11. Engine oil emulsion: sprouting and flowering machine oil emulsion 150x + 40% isocarbophos 1200-1500 times, causing drug damage. Stone-sulfur mixture and Bordeaux can not be sprayed 10-15 days after spraying engine oil emulsion; organophosphorus pesticides shall not be used within 1 week and stone-sulfur mixture shall not be sprayed within 20 days after spraying pine mixture.

12. Permethrin: the use of this drug in orange orchards for more than 2 times will induce an outbreak of mites.

13. Isoprocarb (leaf cicada powder): it is harmful to potatoes.

14. Shachongshuang: it is easy to cause drug damage to cruciferous vegetable seedlings such as cabbage and cabbage and citrus crops. Spraying citrus 300 times in summer will cause leaves and fruits to yellowing.

15. Insecticidal order: it is harmful to cotton and beans.

16. Yitaibao: sensitive to Chinese cabbage seedlings.

17. Kexian Powder: it is not recommended to be mixed with Bombyx mori insecticides, because Bombyx mori toxin insecticides are rapidly degraded into highly toxic Bombyx mori venom.

18. Add rice: it is slightly harmful to soybeans and lotus roots, so you should pay attention to it when using it near soybeans and lotus roots.
