Mesosulfuron-methyl and clodinafop-propargyl compounded herbicide suspending agent and its preparation method

Abstract

The invention, which relates to a mesosulfuron-methyl and clodinafop-propargyl compounded herbicide suspending agent and its preparation method, belongs to the technical field of pesticides. The herbicide suspending agent comprises the following components of: by weight, 0.1-40% of mesosulfuron-methyl with the concentration of 95%, 0.1-40% of clodinafop-propargyl at the concentration of 98%, 0.1-2% of an antifoaming agent, 0.5-20% of a wetting agent, 0.5-20% of a dispersant, 0.1-4% of an antifreezing agent, 0.1-5% of a thickening agent, 0.1-4% of a pH regulator, 0.1-10% of a stabilizing agent, 0.1-5% of an osmotic agent, and the balance being deionized water. The mesosulfuron-methyl and clodinafop-propargyl compounded herbicide suspending agent has advantages of high efficiency, low toxicity and no pollution, and is not easy to become resistant to the environment, human and livestock safety as well as weeds.

Description

technical field

[0001] The invention relates to a herbicide suspending agent compounded by mesosulfuron-methyl and clodinafop-propargyl and a preparation method thereof, belonging to the technical field of pesticides. Background technique

[0002] Pesticide preparations are gradually developing towards safety, environmental protection, and water-based. Pesticide suspension concentrates have the following advantages: ① no dust hazard, safe for operators and the environment; ② using water as the dispersion medium, there is no flammable and Injury problem; ③Compared with wettable powder, it is allowed to use different particle sizes of the original drug, so as to achieve the best biological effect and physical stability of the preparation; ④Liquid suspension spreads well in water and can be directly made into spray liquid Use; ⑤ specific weight, small packaging volume. ⑥The dispersibility and spreadability of the suspension are relatively good, the suspension rate is high, the...
