Imidacloprid tobacco is a super-efficient, broad-spectrum and endogenous herbicide used in soybean field. It has good control effect on annual grasses and broad-leaved weeds. However, it has a long residue time in soil and degrades slowly under alkaline conditions, which is easy to cause drug damage to sensitive crops in the following crop.

The variety was successfully developed in 1984 and was widely used from the late 1980s to the early 1990s.

Imidacloprid tobacco belongs to imidazolinone herbicides. It is a side chain amino acid synthesis inhibitor, which is applied before or after budding. It has excellent control effects on gramineous weeds and some broad-leaved weeds in soybean and other leguminous plant fields, such as amaranth, polygonum, quinoa, solanum, Xanthium sibiricum, barnyard grass, setaria, horse tang, millet, etc. It can be made into water agent.

Spraying method: Seedling Stage (soybean true leaf stage to 2 leaf leaf stage, weed 1~4 leaf stage), 1000 hectare 2000ml5% water agent per hectare, evenly spray 450 ~ 600kg of water. When planted at seedling stage (soil moisture condition is good), water agent of 1500 ~ 2250ml5% per hectare is evenly sprayed to 450 ~ 600kg of water.

Notes: Apply the medicine evenly and thoughtfully, avoid repeating the application, only once a year. Avoid aerial spraying; do not drift to sensitive crops when spraying.

Sensitive crops include beet, cabbage, rape, watermelon, cucumber, potato, eggplant, pepper, tomato, sorghum and so on. The above crops can not be planted in the second year and beet can not be planted in three years.

The preparation is suitable for soybean producing areas in Northeast China. The unused areas should be tested and popularized under the guidance of agricultural technology departments.
