Abstract

The invention provides an additive composition for improving compatibility of a pesticide preparation and a concentrated fertilizer as well as a preparation method and application of the additive composition. The salt resistance and physical stability of a mixed preparation under an electrolysis system can be improved by introducing a compatible additive, a sugar-containing derivative, alcohol ether sulfosuccinate monoester disodium salt and an organic silicon additive. Meanwhile, the invention further provides application of the auxiliary composition for improving the compatibility of the pesticide preparation and the concentrated fertilizer, in particular to application to improvement of compatible stability of a flight control package preparation, increase of the deposition amount of aconcentrated mixed solution on a target and retention and increase of complete biological effects of the pesticide preparation and the concentrated fertilizer.

Description

technical field [0001] The invention belongs to the technical field of pesticide adjuvants, and more specifically relates to an adjuvant composition for improving the compatibility of pesticide preparations and concentrated fertilizers, as well as its preparation method and application. Background technique [0002] In modern agriculture, it is often necessary to use a large amount of pesticides and fertilizers to improve the yield and quality of commercial crops. Typically, single or multiple pesticides and fertilizers are mixed and diluted in water about 10-500 times their own volume, applied by spraying or other means, in order to achieve an optimal range of product control, efficacy, and delivery efficiency. The active ingredients of liquid fertilizers usually contain acid functional groups such as carboxylic or phosphonic acids and are in the form of water-soluble salts containing one or more compounds selected from NH 4 + 、Na + 、K + , Ca 2+ , Mg 2+ , Fe 2+ , Fe ...
