Embodiment Construction

[0022] The present invention is illustrated by the following examples and comparative examples, and specific examples are shown in Table 1.

[0023] Each component weight percent content in the concrete embodiment of table 1

[0024]

[0025] The preparation process of the embodiment: the amount of input of various raw materials is according to the formula amount, first add 800Kg of water to start stirring, and then add the calculated amount of raw materials acetone, glycerin, ferric chloride, pyrithrimol sulfonate, azoxystrobin, and yellow Raw gum, stir evenly, then place the material in batches in an emulsifier for emulsification, keep the emulsification time for 30 minutes, and finally grind the emulsified material through a sand mill.

[0026] Examples 1 to 6 were tested for pH value, long-lasting foaming and thermal storage stability, and all of them met the standards through testing of Examples 1 to 4 (see Table 2 for details).

Abstract

The invention discloses an agricultural bactericidal composition containing bupirimate and azoxystrobin. The agricultural bactericidal composition is prepared from effective components including the bupirimate and the azoxystrobin. The agricultural bactericidal composition solves the problem of insecticide resistance caused by long-term use of single doses of two products, namely the bupirimate and the azoxystrobin separately, and a mixture of the bupirimate and the azoxystrobin has the obvious synergism on controlling powdery mildew.

Description

technical field [0001] The present invention relates to the technical field of compound pesticides, more specifically, it relates to an agricultural bactericidal composition, and it further relates to an agricultural bactericidal composition containing pyrimethrin and azoxystrobin. Background technique [0002] Powdery mildew is a plant disease caused by fungi of the family Erysiphacesae. For example: cereal powdery mildew caused by Erysiphe graminis; powdery mildew of melons, beans, hemp and other plants caused by Sphaerotheca fuliginea; Powdery mildew of grapes caused by Uncinula necator; powdery mildew of more than 80 kinds of trees such as mulberry, pear, persimmon, walnut, chestnut, litchi and papaya caused by Phyllactinia corylea; monofilament of rose Powdery mildew of Rosa flowers caused by Sphaerotheca pannosa. [0003] In the prevention and control of powdery mildew, at present, it mainly relies on fungicides such as imidazoles, triazoles, and methoxyacrylates. D...
