Description
The assistant composition that the present invention relates to use in the pesticidal preparations particularly comprises the assistant composition of at least a corrosion inhibitor and at least a non-ionic surface active agent.
Agricultural chemicals is to be used to alleviate, control or to eliminate material to people or economic prejudicial plant or animal.Agricultural chemicals comprises algicide, disleave desiccant, weed killer herbicide, plant growth regulator, and they are used for regulating the population that competes or parasitize the noxious plant on crop or the observation of plant with crop or ornamental plants.Other agricultural chemicals comprises attractant, bactericide, insecticide, miticide (miticides), miticide (acaricides), invertebrate poison, nematocide, repellant and rodenticide, they are mainly used to reduce parasitism and disease propagation in the domestic animal, the loss of crop, plant, the breaking-up of processed food, textile and wood products and parasitism in the fluid and disease propagation.These destroy normally because the feed behavior of pest.Cognitive " pest " comprises for example bird, mouse, rabbit, mouse, insect, mite, lice, eelworm, slug and snail.
There is the compound more than 800 kinds to be used as agricultural chemicals.Agricultural chemicals can be made up of the inorganic matter that contains sulphur, lead, arsenic or copper, and above-mentioned institute's organic/inorganic substance all has the character of killing livestock.In addition, agricultural chemicals can contain the organic matter that is extracted by plant such as Dalmatian chrysanthemum, tobacco and rotenone.The quantity of organic biocide is in continuous increase.Widely different in the generation of the toxicity of these organic biocides, specificity, persistence and harmful derivative.
Have found that the effectiveness of many agricultural chemicals can be improved by adding auxiliary agent.For example, auxiliary agent can be used in the weed killer herbicide (plant protection composition) processing and/or the stable adminicle as herbicide formulations or spray solution.For chemistry and/or the physical characteristic that improves or improve some agricultural chemicals, can add auxiliary agent and form the spraying mixture.Because spray application is vital to pesticidal properties, therefore add problem such as chemical stability, incompatibility, solvability, suspension, foaming, drift evaporation, volatility, poisoning, surface tension, drop size and the cover degree that auxiliary agent is used with minimizing.Have found that that auxiliary agent can improve is wetting, diffusion, adhesion, emulsification and dispersive property.
