Abstract

The invention discloses a compound pesticide wetting agent and application of the compound pesticide wetting agent in the preparation of pesticide preparations. The compound pesticide wetting agent is characterized in that oxine-copper and tebuconazole are taken as pesticide active ingredients, properties such as the wetting efficiency, the medicine-holding quantity of leaves and the like are taken as evaluation indexes to screen the combinations of different varieties of wetting agents and the dose proportions of the wetting agents, and finally the compound wetting agent capable of effectively improving wetting and spreading capacities of the pesticide preparations and improving the effects for preventing and controlling crop diseases is obtained. The compound wetting agent consists of isomerous 1307 and a penetrating agent JFC and is capable of effectively improving properties such as the wetting efficiency, the medicine-holding quantity of leaves and the like of the pesticide preparations, and the prevention and cure efficiency of a pesticide suspension agent to crop diseases can be effectively improved. The invention further provides a oxine-copper.tebuconazole pesticide suspending agent, a oxine-copper pesticide suspending agent and preparation methods of the oxine-copper.tebuconazole pesticide suspending agent and the oxine-copper pesticide suspending agent and further discloses application of the oxine-copper.tebuconazole pesticide suspending agent and the oxine-copper pesticide suspending agent in the prevention and control of the bacteria or fungal diseases of crops.

Description

technical field [0001] The present invention relates to a pesticide adjuvant, in particular to a pesticide composite wetting agent. The present invention further relates to the use of the pesticide composite wetting agent in the preparation of pesticide suspensions, water-dispersible granules, and wettable powders. , belongs to the field of pesticide wetting agent. Background technique [0002] Wetting agent is a necessary adjuvant component of basic pesticide dosage forms such as suspension concentrate, water dispersible granule, wettable powder, etc., and is also a necessary spray adjuvant component of pesticide application technology. Pesticide wetting agents achieve wetting and permeability by reducing the surface tension, increasing the contact of the drug-containing liquid to the solid surface of the treatment object, and changing the contact angle of the liquid droplet on the surface. There are many kinds of wetting agents, including natural wetting agents, such as t...
