Abstract

The invention discloses a trifluralin micro-capsule suspending agent and preparing methods thereof.According to the formula, the trifluralin micro-capsule suspending agent is prepared from, by mass, 10-60% of trifluralin, 1-6% of an oily capsule material, 1-6% of a water-based capsule material, 5-15% of a dispersing agent, 0.1-1% of a defoaming agent, 0.5-6% of a thickening agent, 0.2-1% of preservative and the balance water.The provided trifluralin micro-capsule suspending agent is environmentally friendly, safe, low in toxicity, long in duration time of the pharmacological function, high in use ratio and capable of reducing phytotoxicity and avoiding negative production reduction of crops.In addition, the two preparing methods of the trifluralin micro-capsule suspending agent are high in safety factor and free of waste water and waste residue emission, and steam exhausted is nontoxic and inodorous and meets the requirement of environment protection.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a trifluralin microcapsule suspension and a preparation method thereof. Background technique [0002] Trifluralin is a pre-emergent herbicide used to control annual weeds in cotton and forage bean fields. Trifluralin is volatile, easy to photolyze, has a very small water solvent, and is not easy to move in the soil layer. It is a selective pre-emergent soil treatment agent, mainly absorbed through the coleoptile and hypocotyl of weeds, and is ineffective for weeds that have been unearthed. Poaceae and some broad-leaved weeds with small seeds are effective and last for a long time. [0003] For a long time, the main formulation of trifluralin has been emulsifiable concentrate. Containing a large amount of organic solvents in the emulsifiable concentrate has unsafe factors such as flammability, explosion, and toxicity. At present, my country has included the formu...
