Embodiment 1

[0029] Biological Assay Example 1: Indoor Joint Toxicity Determination Test of Flupirfurone and Lufenuron Compound on Chive Tardigrade

[0030] Test object: Bradysia odoriphaga (Yang et Zhang), the leek pseudostem was raised artificially for seven generations in the incubator.

[0031] Test method: The test refers to the "People's Republic of China Agricultural Industry Standard NY / T 1154.14-2008" and uses the leaf soaking method for determination.

[0032] When CTC≦80, the composition exhibits antagonistic effect; when 80

[0033] Measured toxicity index (ATI) = (standard drug LC 50 / Test agent LC 50 )×100

[0034] Theoretical toxicity index (TTI) = Toxicity index of agent A × percentage of A in the mixture + toxicity index of agent B × percentage of B in the mixture

[0035] Co-toxicity coefficient (CTC) = [measured toxicity index (ATI) of mixture / theoretical tox...

[0041] Biological Assay Example 2: Indoor Combined Toxicity Test of Flupirfurone and Lufenuron Compound on Bemisia tabaci

[0042] Test object: Bemisia tabaci Gennaduid, artificially reared indoors for multiple generations, and picked consistent 4th instar nymphs for the experiment.

[0043] Test method: The test method refers to the "People's Republic of China Agricultural Industry Standard NYT 1154.4-2006". Using rice stem soaking method.

[0044] Table 2. Indoor combined toxicity test results of flurpirfurone and lufenuron against Bemisia tabaci

[0046]

[0047] From the test results in Table 2, it can be seen that when the ratio of flupyrfurone and lufenuron is between 50:1 and 1:50, the co-toxicity coefficients against whitefly are all above 120, which has synergistic effect The effect, especially when the ratio is between 10:1 and 1:10, the synergistic effect is the most obvious, and the co-toxicity coefficients are all above 190.

Embodiment 1

[0049] Preparation Example 1: 51% Flupyrfurone Lufenuron Suspension Concentrate

[0050] Flupyrfurone 50%, Lufenuron 1%, Phenylphenol Polyoxyethylene Ether Phosphate 3%, Sodium Alkyl Naphthalene Sulfonate 3%, Methylcellulose 3%, Glycerol 3%, Silicone Oil 0.8%, deionized water makes up 100%. The above-mentioned ingredients are processed according to conventional methods to obtain a 51% flurpirfurone·lufenuron suspension concentrate.

Abstract

The invention discloses an insecticidal combination containing flupyradifurone. Effective ingredients of the insecticidal combination are flupyradifurone and lufenuron, the mass ratio of flupyradifurone to lufenuron is (1:50)-(50:1). The combination has an obvious synergistic effect, can reduce pesticide dosage and is favorable for treating pesticide resistance of pests and suitable for treating Chinese chive maggots, whiteflies, leaf miners, thrips, aphids and icerya purchasi and the like on rice, vegetables and fruit trees.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing flurpirfurone and its application in controlling small pests on crops, and belongs to the technical field of compound pesticides. Background technique [0002] Small pests such as Homoptera, Diptera and Thysanoptera are widespread worldwide pests, especially pests such as chive maggots and whitefly are extremely serious in our country, causing serious economic losses. Among them, chive maggots mainly harm lily vegetables such as leeks, green onions, onions, shallots, and garlic, and are one of the main pests of onion and garlic vegetables; while whiteflies seriously harm vegetables such as tomatoes, cucumbers, peppers, and many crops such as cotton; In addition, pests such as aphids, leaf miners, thrips and scale insects can cause quality degradation and seriously affect economic value. At present, my country mainly uses imidacloprid, pymetroz...
