Instructions:
1. Soybean field weeding soybeans before sowing or before sowing, soy field weeding generally used herbicide 137 ~ 167 ml (active ingredient 66.7 ~ 80 grams), organic matter content greater than 3% of clay loam with high volume, organic matter less than 3% The sandy soil is used in low amounts. The high soil moisture is conducive to the absorption of the medicament, and shallow soil is required under drought conditions. Use 48% chlorhexidine emulsifiable concentrate 0.75-1 liters per hectare (50-67 ml per acre) with 50% acetochlor EC 1.5 liters (100 ml per acre) or 70% sikhot WP 550 g per hectare ( Mixing 30 grams per acre, knapsack sprayer spray, 300-450 liters per hectare (20-30 liters per acre), tractor sprayer more than 200 liters per hectare.
2. Sugarcane weeding sugarcane before planting, before germination, use 48% emulsifiable oil 1-1.5 liters per hectare, add water 450 liters (66.7-100 ml per acre, add water 30 liters) sprayed on the soil surface, against valerian, foxtail, cattle It has good control effect on glutinous grass, Huoxiang scorpion, hot pepper, purslane, and anti-twig. It is safe for sugar cane. It is also suitable for sugar cane intercropping peanuts and soybeans. It is suitable for cane and rice rotation.
3. Paddy field weeding and transplanting in the field for 3-5 days, 稗 grass 1.5 leaf period, with 48% emulsifiable oil 375-450 ml per hectare (ml (25-30 ml per acre), herbicide method to control weeds, rain Weeds such as long flowers, but the perennial weeds are poorly effective. 48% chlorhexidine emulsifiable concentrate can be used in 300-375 ml per hectare (20-25 ml per acre) and 10% turpentine 150 g (10 g per acre) or 10%. When the farmer gets 225 grams (15 grams per acre), it is mixed with the soil and water, and it is kept 3-5 centimeters. It is normally managed after 3-5 days. It has a wide spectrum of killing grass and is safe for rice.
