Pesticides "These five types of pesticides are most likely to cause phytotoxicity, you don’t even know"

Triazoles 1.
Varieties: 1.
Strong inhibition: triadimefon, triadimenol, tebuconazole, hexaconazole, diniconazole, propiconazole, flusilazole, epoxiconazole, paclobutrazol, weak inhibition: Difenoconazole, fenbuconazole, myclobutanil two, emergence of key crops: 1.
Sensitive: all kinds of fruit trees in the Rosaceae, vegetables such as tomato, eggplant, pepper potato and other Solanaceae, melon crops in watermelon, bitter gourd Cucumbers are more sensitive.
First, melons, pumpkins, and northern melons are relatively better.
In general, melons are more sensitive, cruciferous vegetables, umbelliferous vegetables, and so on
.
2.
Insensitive: wheat, corn, rice, etc.
Gramineae, beans, soybeans, peanuts and other legumes
.
3.
Use: 1.
It has a great influence on young fruits, young flowers, young leaves, young and tender parts and fast-growing parts.
Use weak inhibitory drugs as appropriate
.
3.
Do not use drugs with strong inhibitory properties during the seedling, young fruit, flowering, and shoot budding period
.
4.
Disease prevention and control: Prevention and treatment of higher fungi: powdery mildew, rust, anthracnose, scab, fungal leaf spot, early blight, white rot and so on
.
Sulfur 1.
Varieties: 1.
Inorganic sulfur: lime sulfur mixture, sulfur powder, sulfur suspension, sulfur steamer, sulfur fumigator 2.
Organic sulfur: ethyl allicin 2.
Use: lime sulfur mixture: sterilization and insecticide , Kill eggs, clear the garden
.
To clean the garden, use 3-5 Baume degrees to spray the ground trunks and branches.
The roots and shoots and fruits should be sprayed at 0.
3-0.
5 Baume degrees.
The temperature above 30 degrees cannot be sprayed
.
Copper preparations 1.
Varieties: 1.
Inorganic copper: Bordeaux liquid: quicklime and copper sulfate, basic copper sulfate, copper hydroxide, copper king, cuprous oxide 2.
Organic copper: copper quinoline, copper thiazide, thiophene Mori Copper, Copper Rosinate, Copper Amino Acid, Copper Succinate Fertilizer, Copper Acetate 2.
Sterilization Principle: The structure of protein is destroyed by copper ions and leads to necrosis
.
3.
Prevent diseases: Fungi: downy mildew, bacteria: bacterial wilt, leaf spot, angular spot, ulcer, etc.
, virus, rhizobia, slime mold
.
Only try surface diseases, no systemic sterilization
.
If the humidity is high for a long time, it will be prone to phytotoxicity or if the dew is too heavy, it will be prone to phytotoxicity.
IV.
Use: 1.
The concentration can not be adjusted casually, and the temperature can not be used if the temperature is too high
.
2.
Inorganic copper is recommended to be used alone, and organic copper should be prepared and sold
.
3.
Inorganic sulfur and copper-containing fungicides should be used separately, and the methoxy acrylate fungicides should be used at intervals of more than 15 days.
1.
Varieties: azoxystrobin, azoxystrobin, pyraclostrobin, trifloxystrobin Lipid, Enoximone, Picoxystrobin II.
Use: 1.
Use it alternately with other types of fungicides when using it
.
2.
Use small seedlings and tender parts to reduce the concentration
.
3.
Methoxyacrylate fungicides have strong permeability and cannot be mixed with silicone additives or emulsifiable concentrates
.
Amides 1.
Variety: succinate dehydrogenase inhibitor set: velocirap, thiafluzamide, fluopyram, fluconazuramide, 2.
Use: 1.
Vegetables and fruit trees themselves will cause phytotoxicity 2 , Can not be used in combination with silicone additives or emulsifiable concentrates.
3.
Can not be used under high temperature conditions.
4.
Can not be mixed with metal ions.
Can not be mixed with manganese, zinc and calcium.
5.
It is recommended to use alone or test in advance before use
