"Two Seals and Two Supplements" Control Machine Inserting Rice Field Weeds

Machine inserted into the late planting, planting row spacing, small seedlings, weak competitiveness of weeds, grass affected by a greater impact, at the same time due to weak seedlings, mechanical damage, etc., in addition to often appear phytotoxicity. After many years of field trials and demonstrations, machine-inserted rice fields adopt the “two seals and two fills” method of weeding, which can effectively solve the problems of grass and rice pests and phytotoxicity.
Two seals (1) Before the planting, they should seize and kill first, and then use 46% of benzylpyridylthiophene wettable powder for 60 to 100 grams per mu, and mix and spread the bottom fertilizer to spread the water for 3 to 5 days. Only irrigation does not drain. (2) Fields that have not been soil-blocked prior to planting can be planted for 5 to 10 days after transplanting; or fields that have been soil-blocked before transplanting can be used 15 to 20 days after transplanting. Jia Jiabao 46% benzylpyridyl thiophene wettable powder 60 ~ 100 grams or Yelao Yangge 25% benzamide microfine granules 150 ~ 200 grams, dubbed fertilizer or medicine soil applicator. Keep a shallow water layer during application and keep water for 3 to 4 days after application. Be careful that water does not drown.
Two supplements (1) The plot of heavy gold occurs in the plot. Each mu of wild old rice laughs with 10% cyhalofop-butyl ester EC 60-100 ml of water plus 10-15 kg of water spray, with high concentration of fine spray. Dry field water before application, rehydration 24 hours after application, water retention for 3 to 5 days. (2) For perennial sedges and broad-leaved grasses, at the end of rice tillering, weeds 3 to 7 leaves, 10% bensulfuron WP per mu, 30 to 45 grams, plus 48% antiseptic powder 100 ml or 56% 2 alpha 4 sodium chloride soluble powder 60 to 100 grams, add water 40 to 50 kg spray. Before the application of pesticides, dry the field water, rehydrate after 1 to 2 days after application, and keep water for 3 to 5 days.
