Embodiment 1

[0047] Example 1: 20% fluopyram chitosan emulsifiable concentrate

[0048] Components and percentage by weight are as shown in Table 2:

[0049] Table 2

[0050] fluopyram 19％ Chitosan 1％ Calcium dodecylbenzenesulfonate 5％ Alkylphenol polyoxyethylene ether 8％ sodium lauryl sulfate 7％ Dimethyl sulfoxide (solvent) 5％ Xylene (solvent) margin

[0051] Mix and stir fluopyram, chitosan, co-solvent and solvent in Table 2 to completely dissolve fluopyram and chitosan, then add other additives and stir evenly to obtain 20% fluoride Pyramipram Chitosan EC.

Embodiment 2

[0052] Example 2: 30% fluopyram·chitosan wettable powder

[0053] Components and weight percentages are as shown in the table:

[0054] table 3

[0055] fluopyram 28％ Chitosan 2％ Fatty alcohol polyoxyethylene ether 8％ Sodium lignosulfonate 4.5％ Naphthalenesulfonic acid formaldehyde condensate sodium salt 6％ Kaolin margin

[0056] Mix fluopyram with chitosan and other ingredients according to the formula in Table 3 above, stir evenly in a stirring tank, pulverize with a jet mill and mix evenly to make 30% fluopyram chitin Polysaccharide wettable powder.

Embodiment 3

[0057] Example 3: 40% fluopyram·chitosan water dispersible granules

[0058] Components and percentages by weight are shown in Table 4:

[0059] Table 4

[0060]

[0061]

[0062] Mix the materials in Table 4 evenly, pulverize them with an ultra-fine jet mill, knead them, and then add them to a fluidized bed granulation dryer for granulation, drying, and sieving to prepare 40% fluopyram chitin Polysaccharide water dispersible granules.

Abstract

The invention relates to a composition containing fluopyram and chitosan and application of the composition. The composition contains the effective components including the fluopyram and the chitosan in a weight ratio of (50-1) to (1-50), and the sum of the effective components is 0.1%-80% of total weight of the composition. The composition can be prepared into agriculturally acceptable dosage forms such as missible oil, wettable powder, water dispersible granules, microemulsions, suspending agents, water emulsions and granules. The composition has the beneficial effects that the components are reasonable, and the control effects on nematodes and fungal diseases of plants are good; the insecticidal and sterilizing effects are not only the simple superposition of the activity of each component, and compared with a single preparation, the composition has remarkable insecticidal and sterilizing effects; and the dosage is reduced, the pesticide residue is reduced, the service life of a pesticide is prolonged, the generation of drug resistance of pests is delayed, the crop safety is good, the stress resistance of crops is remarkably improved, and the yield and quality of the crops are increased.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticidal and fungicidal composition containing fluopyram and chitosan and its application. Background technique [0002] Nematodes belong to the nematode class Nematodes. They are small in size and can only be observed with a microscope. It is common in China and the damage is serious. There are more than 3,000 kinds of nematodes that are harmful to plants, most of which live in the soil, and some also parasitize in plants. Nematodes spread through soil or seeds, which can damage the root system of plants; eating plants directly can greatly reduce the absorption of nutrients and water by plants; nematodes eating plants cause wounds, and also facilitate the invasion of plant pathogens, so that they can interact with fungi, Bacteria and viruses interact to form compound infections, which indirectly spread fungal and bacterial diseases caused by other microorganisms, aggr...
