The sowing and emergence period of wheat is the main period for wheat to prevent diseases. This time, as long as the pesticides are managed ingeniously, the main diseases can be prevented:
First, the pesticide control in the sowing period: several common diseases of wheat, wheat blight, leaf blight, smut, smut, if it is mixed with underground pests, use pesticides: more than 50% can be applied Fu mixed powder (carbendazim: thiram double is 1:1) 500 times liquid soaking for 48 hours or 50% carbendazim wettable powder, 70% thiophanate-soluble wettable powder, 40% seed dressing double 50 100 ml of phoxim emulsifiable concentrate 100 kg, and dried for sowing.
Second, if it is a single wheat whole disease and underground pests mixed areas: the light land block can choose to completely etch 20-30 ml plus water 0.5-0.75 kg, mixed with 10-15 kg of wheat; if it is critically ill Totally etched 20 ml of mixed wheat 6.5-7.5 kg +48% lesbian emulsifiable concentrate is 0.3% seed dressing. After the seeds are mixed, they can be piled up for 6-12 hours. After drying, they can be sown. Because this allows the pesticide to adhere more fully to the surface of the wheat seed, eliminating the disease on the surface of the seed.
3. In the field of wheat sheath blight, root rot and underground pests, 50% thiophanate-methyl or 50% carbendazim 200gl+50% phoxim 100ml can be selected for 100kg seed dressing. You can sow.
Fourth, the emergence period from late October to early November is the best time to control grass weeds.
1. Treat buckwheat: use 3% Shima or Kuoshima 20-30 ml per acre of field, add 30 kg of water spray.
2, treatment of alkali sow: 50% of the use of 50% Wo. Ethyl EC 80-100ml with water 50kg sprayed in the entire field after the wheat seedlings out.
3, treatment of Mai Niang: also in the treatment of wheat after emergence, weeds with 50% isoproturon before tillering, one mu of land can be sprayed with 125-250g water 50kg in the entire field.
