Embodiment 1～12

[0020] Embodiment 1~12 wettable powder

[0021] Mix polyoxin, iproprocarb, dispersant, wetting agent, and filler, mix evenly in a mixing tank, pulverize through a jet mill and mix evenly, then the wettable powder product of the present invention can be made .

Embodiment 1

[0022] Example 1 80% polyoxin · iprocarbamide wettable powder

[0023] Polyoxin 50%, iprocarbamin 30%, polycarboxylate 5%, sodium dodecylbenzene sulfonate 3%, saponin powder 2%, kaolin remainder, the mixture is carried out airflow pulverization, makes 80 % polyamycin · iprocarbamide wettable powder.

Embodiment 2

[0024] Example 2 50.5% polyoxamycin · iprocarbamide wettable powder

[0025] 50% polyoxin, 0.5% iprocarbamin, 4% lignosulfonate, 4% teaku, 8% white carbon black, and the rest of bentonite. The mixture was air-pulverized to obtain 50.5% polyoxin Sodium iprocarbamide wettable powder.

Abstract

The invention discloses a bactericidal composition containing polyoxins and iprovalicarb; and the weight ratio of the polyoxins to the iprovalicarb is (1:100)-(100:1). The composition has relatively high activity on various diseases of various crops and has an obvious synergistic effect, and the bactericidal spectrum is enlarged. The composition has characteristics of small dosage, rainwash resistance and obvious synergism.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a fungicidal composition containing polyoxamycin and iprocarbam on crop diseases. technical background [0002] Iprovalicarb, chemical name: 2-methyl-1-[(1-p-methylphenylethyl)carbamoyl]-(S)-propylcarbamate isopropyl ester, is an amino acid Fungicide-like, the mechanism of action is to affect the metabolism of amino acids. Unlike known fungicides, it has no cross-resistance with fungicides such as metalaxyl. Polyoxin protects and treats crops by inhibiting the growth of sporangia germ tubes, mycelium growth and sporulation. It can effectively control diseases caused by oomycete pathogens. [0003] Polyoxin, a metabolite produced by Streptomyces aureus, belongs to the broad-spectrum antibiotic fungicide. Has better systemic conduction. Its mechanism of action is to interfere with the biosynthesis of chitin in the cell wall of the bacteria, so that the cell w...
