These 5 pesticides are prone to phytotoxicity

note! These 5 pesticides are prone to phytotoxicity, so use with caution! In agricultural production, what are the most commonly used fungicides and pesticides that are most likely to appear and how to use them? Common fungicides include triazoles, sulfur-containing, copper preparations, methoxy acrylates, etc.
Let's learn about these drugs in detail below
.
1.
Varieties: 1.
Strong inhibition: triadimefon, triadimenol, tebuconazole, hexaconazole, diniconazole, propiconazole, flusilazole, epoxiconazole, paclobutrazol, weak inhibition: anisole Cycloconazole, fenbuconazole, myclobutanil, two key crops appearing: 1.
Sensitive: all kinds of fruit trees in Rosaceae, vegetable tomatoes, eggplants, pepper potatoes and other Solanaceae, melon crops are more watermelon, bitter gourd, cucumber Sensitive, first of all, 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-containing agents 1.
Varieties: 1.
Inorganic sulfur: lime sulfur mixture, sulfur powder, sulfur suspension agent, sulfur steamer, sulfur fumigator 2.
Organic sulfur: ethyl allicin 2.
Use: Lime sulfur mixture: can sterilize and kill Insects, kills eggs, clears 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 preparation 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: Destruction of protein structure by copper ions leads to necrosis
.
3.
Prevention of diseases: Fungi: downy mildew, bacteria: bacterial wilt, leaf spot, angular spot, ulcer, etc.
, viruses, rhizobia, slime mold
.
Test only 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 alternate use should be more than 15 days before using Methoxyacrylate fungicides.
1.
Varieties: azoxystrobin, azoxystrobin, pyraclostrobin, oxime Antibacterial lipid, enoxime bacterial lipid, picoxystrobin 2.
Use: 1.
Use it alternately with other types of fungicides when in use
.
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
.
Picture of amides 1.
Variety: Succinate dehydrogenase inhibitor set: velvet, thiafluzamide, fluopyram, flupyramide, 2.
Use: 1.
Vegetables and fruit tree medicines themselves will be phytotoxic 2.
It cannot be mixed with silicone additives or emulsifiable concentrates.
3.
It cannot be used under high temperature conditions.
4.
It cannot be mixed with metal ions.
It cannot be used with manganese, zinc or calcium.
5.
It is recommended to use alone or test in advance.
