Description

Technical Field

[0001] The present invention belongs to the field of pesticides, and in particular relates to a pesticide composition 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, and global change, pesticide resistance, and cropping systems are contributing to their increasing severity. Common hosts of these pests include a variety of economic crops, including the Poaceae, Malvaceae, Leguminosae, Solanaceae, and Cucurbitaceae families. We found that spider mites from the genus Tetranychus were the most common, with Tetranychus truncatus being the most common, 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

All the above technicals are provided by the R&D center of the group;

[0176] Test target: Two-spotted spider mite;

[0177] Select nymphs raised indoors with consistent physiological status. The temperature is (25±1)°C, the relative humidity is 65%±5%, and the photoperiod is 16 / 8h (L / D).

[0178] Select cucumber leaves with uniform growth, use a hole puncher to make leaf discs with a diameter of 2 cm, place agar in a culture dish to keep it moist, place filter paper on it, and place leaf discs on the filter paper, with 3 leaf discs per dish, and inoculate the nymphs raised indoors onto the leaf discs, with 10 to 15 mites on each leaf disc.

[0179] Preparation: Dissolve the original drug in acetone and dilute with a 0.1% Tween-80 solution. Prepare separate single-dose stock solutions. Design five groups of mixes based on the mixing objectives and drug activity. Prepare five series of mass concentrations for each single dose and each mix using the same ratio.

[0180] Chemical treatment: Place the petri dish on the bottom plate of a Potter spray tower and spray with a volume of 1 ml. Allow the solution to settle for 1 minute before removing it from the dish and transferring it to rearing conditions. Each treatment should be replicated at least four times, with at least 120 insects tested at each dose. A blank control containing no chemical (including all organic solvents and emulsifiers) should be used.

[0181] Data Statistics and Analysis: 48 hours after treatment, examine the insects for mortality and record the total insect count and the number of dead insects. Calculate the adjusted mortality rate for each treatment based on the survey data.

[0182] Calculate using the following formula, with the results rounded to two decimal places:

[0183]

[0184] Where:

[0185] P——mortality rate, in percentage (%);

[0186] K——indicates the number of dead insects, the unit is head;

[0187] N——represents the total number of insects processed, in heads.

[0188]

[0189] Where:

[0190] P1——adjusted mortality rate, in percentage (%);

[0191] P t ——Treatment mortality rate, expressed in percentage (%);

[0192] P0 - blank control mortality rate, in percentage (%).

[0193] 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.

[0194] 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.

[0195] The co-toxicity coefficient (CTC value) of the mixture is calculated as follows:

[0196]

[0197] Where:

[0198] ATI - measured toxicity index of mixture;

[0199] S——LC of standard acaricide 50 , the unit is milligrams per liter (mg / L);

[0200] M——LC of the mixture 50 , the unit is milligrams per liter (mg / L).

[0201] TTI=TI A *P A +TI B *P B

[0202] Where:

[0203] TTI – Theoretical Toxicity Index of Mixtures;

[0204] TI A ——Agent toxicity index;

[0205] P A ——The percentage of agent A in the mixture, in percentage (%);

[0206] TI B ——Toxicity index of agent B;

[0207] P B ——The percentage of agent B in the mixture, in percentage (%).

[0208]

[0209] Where:

[0210] CTC – Co-toxicity coefficient;

[0211] ATI - measured toxicity index of mixture;

[0212] TTI - Theoretical Toxicity Index of Mixture.

[0213] 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.
