Embodiment 1

[0037] Experimental method: Refer to the relevant content in GB / T17980.4-2000 "Guidelines for Field Efficacy Experiments of Pesticides (1) Insecticides Control Rice Planthoppers".

[0038] Experimental effect calculation method:

[0039]

[0040]

[0041] The control effect is converted into a probability value (y), and the concentration of the drug solution (μg / ml) is converted into a logarithmic value (x). The toxicity equation and the inhibitory intermediate concentration EC50 (half maximum effect concentration) are calculated by the least square method, and the toxicity index is calculated. The method of calculating the co-toxicity coefficient of the compound agent is to calculate the toxicity index and co-toxicity coefficient (CTC) of the drug.

[0042]

[0043] 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)

Embodiment 2

[0057] Experimental method: Refer to the relevant content in GB / T17980.16-2000 "Guidelines for Field Efficacy Experiments of Pesticides (1) Insecticides Control Greenhouse Whitefly".

[0058] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0059] Experimental results: as shown in Table 2.

[0062]

[0063] Analysis of results:

[0064] 1) The measured toxicity index (ATI) of thiamethoxam and etoxazole was higher than that of toxicity index (TTI) within the weight ratio range of 60:1-1:80.

[0065] 2) The co-toxicity coefficient (CTC) of thiamethoxam and etoxazole is greater than 100 within the weight ratio range of 60:1-1:80, and there is no antagonistic effect; the ratio of thiamethoxam and etoxazole is 4:1- Within the weight ratio range of 1:80, CTC is higher than 120, wh...

Abstract

The invention discloses a thiamethoxam and etoxazole-containing pesticide composition and application thereof, and the composition comprises thiamethoxam and etoxazole with the weight proportion of 99:1-1:99. The dosage form can be one form selected from wettable powder, a water dispersible granule, a water dispersible tablet, a suspension agent, a seed coating agent, missible oil, microemulsion and a solution. The pesticide composition can be used for prevention and protection of pests violation and diseases caused by pests violation at any parts of plants or propagation materials, and can also be applied to plant stems, leaves, seeds, fruits, roots or soil; the pesticide composition has obvious synergistic effect, can reduce pesticide dosage, can significantly lower LC50, and has the advantages of broad insecticidal spectrum, high efficiency, low prevention and treatment cost, and the like.

Description

technical field [0001] The invention relates to a fungicide composition, in particular to a fungicide composition containing thiamethoxam and etoxazole and application thereof. Background technique [0002] The use of pesticides has played a huge role in the process of human transformation of nature, promoted the great development of agriculture, and brought huge economic benefits to human beings. The types of pesticides have gradually transformed from the era of natural and inorganic pesticides dominated by natural medicines and inorganic compound pesticides to the era of organic synthetic pesticides. Due to the toxicity and side effects of pesticides, a series of problems have appeared in the process of long-term use of pesticides, such as toxic residues of pesticides, environmental pollution, ecological balance damage and so on. Especially after the 1990s, new varieties of pesticides in the world were constantly updated, crop pests and pest mites were frequently used for...
