Embodiment 1

[0015] Example 1: Toxicity determination of fluopyram and astragalus polysaccharide complex against cucumber powdery mildew

[0016] Test object: Cucumber powdery mildew (Erysiphe cichoracearum)

[0017] Test method: Potted plant method is adopted. Cucumber powdery mildew varieties are susceptible to sowing, cultivated in pots to the stage of 2-4 true leaves, and numbered for later use. Use pure water with a small amount of surface active substances to absorb fresh spores from cucumber leaves covered with powdery mildew bacteria to make a spore concentration of 1×10 5 individual / mL spore suspension for later use. On the basis of the preliminary test, according to the activity of the drug, 5 series of gradient concentrations were set. Spray the liquid medicine evenly on the leaf surface until it is completely moistened, and wait for the liquid medicine to dry naturally for later use. For each treatment, 3 pots were repeated 4 times, and the treatment containing only solvent...

Embodiment 2

[0040] Example 2: 18.0% fluopyram · astragalus polysaccharide suspension

[0041] Formula: take by weighing fluopyram 16.0%, astragalus polysaccharide 2.0%, alkyl naphthyl sulfonate 3.0% (wetting agent), polycarboxylate 3.2% (dispersant), xanthan gum 0.2% ( thickener), ethylene glycol 2% (antifreeze), 0.2% silicone oil (defoamer), and deionized water to make up to 100%. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to make the particle size of all particles below 5 μm, and then 18.0% fluopyram·astragalus polysaccharide suspension can be prepared.

[0042] Adopt above-mentioned 18.0% fluopyram · astragalus polysaccharide suspension to control grape powdery mildew, dilute 18.0% fluopyram · astragalus polysaccharide suspension 2000 times, carry out uniform spraying in the initial stage of grape powdery mildew, with spraying wet leaves Accurately, the pesticide was applied again at an interval of 7 days, and the pesticide w...

Abstract

The invention relates to a sterilizing composition containing fluopyram and astragalus polysaccharide. The sterilizing composition is prepared from effective constituents, i.e., the fluopyram and theastragalus polysaccharide with the weight ratio being (1 to 25):1. The sterilizing composition provided by the invention has a remarkable synergistic effect on crop powdery mildew, can effectively control diseases, and has the efficacies of saving time, labor and effort.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a bactericidal composition containing fluopyram and astragalus polysaccharide. Background technique [0002] Fluopyram, English name: fluopyram, is a new type of pyridylethylbenzamide fungicide and nematocide developed by Bayer, which acts on the mitochondrial respiratory chain and inhibits the activity of succinate dehydrogenase (complex II) Thereby blocking the electron transfer, resulting in the inability to provide the energy demand of the body tissue, and then killing the control object or inhibiting its growth and development. Fluopyram is an effective agent for the control of powdery mildew and sclerotinia, but it is expensive to use alone and has the risk of developing resistance. [0003] Radix Astragalus (Radix Astragalus), a leguminous plant, is divided into Mongolian Astragalus and Capsular Astragalus. Astragalus polysaccharides (APS) is the main active ingred...
