Bentazone Solution 25%This product is a contact killing, selective post seedling herbicide. Seedling stage treatment works through leaf contact. When used in dry fields, inhibition of photosynthesis is carried out through leaf infiltration into chloroplasts; When used in paddy fields, it can also be absorbed by the root system and transmitted to the stems and leaves, hindering weed photosynthesis and water metabolism, leading to physiological dysfunction and death. Mainly used to control dicotyledonous weeds, paddy sedge, and other monocotyledonous weeds, it is therefore a good herbicide for rice fields. It can also be used for weeding dry field crops such as wheat, soybeans, cotton, peanuts, etc., such as clover, sedge, duck tongue grass, cowhide felt, flat scirper grass, wild water chestnut, pig weed, polygonum grass, amaranth, quinoa, knot grass, etc. The effect is good when used in high temperature and sunny days, but the effect is poor when used in reverse.
