Abstract

The invention discloses a weedicide with systemic conductibility and contact killing performance and a preparation method thereof, and particularly relates to the technical field of a cooperative composition of the weedicide. The weedicide is prepared from raw materials in gram by weight: 48 to 150g of bentazone raw medicine, 20 to 60g of butyl ethyl trichloropyloxy acetate, a sufficient quantityof organic solvents, a proper quantity of emulsifying agents and a proper quantity of cosolvents, wherein the organic solvents are one or several materials from methylbenzene, xylene, solvent oil, cyclohexanone, acetone and N,N dimethylformamide. The bentazone and trichlopyr are combined with stem leaf spray to be used; most broad leaves and sedge weed can be eliminated; the weedicide can be spread to the sagittaria trifolia roots; the corm is thoroughly killed; the weed recurrence can be effectively prevented, so that weeds cannot cause harm to the rice growth; the weedicide consumption is also reduced; the weedicide application cost is reduced; meanwhile, no influence is caused on the tillering rate of the rice; the rice yield stability is ensured.

Description

technical field [0001] The invention relates to the technical field of synergistic composition of herbicides, more specifically, the invention relates to a herbicide with both systemic conductivity and contact killing properties and a preparation method thereof. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, and are a class of substances used to eliminate or inhibit plant growth. In daily life, herbicide is one of the very common pesticides, which is of great significance to increase my country's grain production. As a very common weed in rice fields, Arrowhead Arrowhead is a perennial herb with stems and bulbs. Because the roots and stems of Arrowhead Arrowhead are deeply distributed, it has strong reproductive ability and wide adaptability. characteristics, making it difficult for ordinary herbicides to effectively kill arrowroot. [0003] The invention patent of patent application publica...
