Description

Technical Field

[0001] The present invention belongs to the field of pesticides, and in particular relates to a pesticide composition containing a diphenyl sulfide compound and application thereof. Background Art

[0002] Phytophagous mites are significant pests of many agricultural crops worldwide. If not controlled below economic thresholds, they threaten food, feed, and fiber production. In particular, species of mites from the Tetranychidae, Tenebrionidae, Tarsonematidae, and Mycobacteridae families are significant pests, directly feeding on plants or transmitting plant pathogens and viruses, harming crops.

[0003] Spider mites are a major agricultural pest, encompassing over 100 species. Their small size makes them difficult to identify. Coupled with global change, pesticide resistance, and cropping systems, spider mite damage is becoming increasingly severe. Common hosts for these pests include a variety of economic crops, including the Gramineae (corn), Malvaceae (cotton, hollyhock), Leguminosae (soybean, mung bean, red bean, common bean), Solanaceae (potato, eggplant, tomato, pepper), and Cucurbitaceae (cucumber, pumpkin, tomato, watermelon, winter melon). We found that the most common species of spider mites are Tetranychus truncatus, followed by Tetranychus pueraricola, Tetranychus kanzawai, and the red and green forms of Tetranychus urticae. These important agricultural pests are particularly susceptible to developing pesticide resistance due to their short reproductive cycles, high reproductive output, low mobility, and high self-fertilization.

[0004] For a long time, chemical control has been the primary method for controlling spider mites in production. The widespread use of chemical insecticides has made spider mites one of the most resistant pests. Reasonable chemical compounding or mixing has the positive advantages of expanding the insecticide spectrum, improving control effectiveness, extending the optimal application period, reducing dosage, minimizing pesticide damage, reducing residues, and delaying the development of pesticide resistance in pests. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, the present invention provides a pesticide composition containing a diphenyl sulfide compound and its use. This pesticide composition effectively controls a variety of plant-feeding mites, exhibiting synergistic effects within a certain ratio range. It can broaden the spectrum of mites, reduce costs, minimize dosage, extend the duration of efficacy, and slow the development of resistance.

[0175] If the control mortality rate is less than 5%, no correction is required; if the control mortality rate is between 5% and 20%, correction should be made; if the control mortality rate is greater than 20%, the test needs to be repeated.

[0176] The data were processed using the probability value analysis method. The LC of the toxicity regression line can be obtained by using the IBM SPSS Statistics 20 statistical analysis system. 50 The activity of the test agent on the biological test material was evaluated by using the b value and its 95% confidence limit.

[0177] The co-toxicity coefficient (CTC value) of the mixture is calculated as follows:

[0178]

[0179] Where:

[0180] ATI - measured toxicity index of mixture;

[0181] S——LC of standard acaricide 50 , the unit is milligrams per liter (mg / L);

[0182] M——LC of the mixture 50 , the unit is milligrams per liter (mg / L).

[0183] TTI=TI A *P A +TI B *P B

[0184] Where:

[0185] TTI – Theoretical Toxicity Index of Mixtures;

[0186] TI A ——Agent toxicity index;

[0187] P A ——The percentage of agent A in the mixture, in percentage (%);

[0188] TI B ——Toxicity index of agent B;

[0189] P B ——The percentage of agent B in the mixture, in percentage (%).

[0190]

[0191] Where:

[0192] CTC – Co-toxicity coefficient;

[0193] ATI - measured toxicity index of mixture;

[0194] TTI - Theoretical Toxicity Index of Mixture.

[0195] A co-toxicity coefficient (CTC) of 120 or higher indicates a synergistic effect; a co-toxicity coefficient (CTC) of 80 or lower indicates an antagonistic effect; and a co-toxicity coefficient (CTC) of 80 or lower indicates an additive effect.
