Embodiment 1

[0018] Example 1: Toxicity determination of hexythiazox and fluazinam and different ratios to Panonychus citrus

[0019] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". The adult females of Panonychus citrus collected from the field were reared indoors for 30 generations, and the adult females with uniform growth were selected as the test insects. The small seedling method is adopted, that is, 120 live adult mites of whole clawed mites are connected to small pots of citrus seedlings, and the seedlings with mites are sprayed with a spray tower, moved to 25 ° C, and cultivated at a relative humidity of 90%. After 15 days, check and record Survival number, use DPS data processing software for statistical analysis, calculate regression curve, and calculate LC 50 , using the co-toxicity coefficient method (CTC) proposed by Sun Yunpei et al. in 1960 to evaluate the synergistic effect of drug mixing. The formula for calcul...

Embodiment 2

[0032] Example 2: 18% Hexythiazox Fluazinam Suspension Concentrate

[0033] Formula: weigh hexythiazox 3.0%, fluazinam 15.0%, glycerin fatty acid ester polyoxyethylene ether 2.5% (dispersant), alkylnaphthalene sodium sulfonate 3.5% (wetting agent), xanthan Glue 1.5% (thickener), organosilicon 0.2% (defoamer), ethylene glycol 2.5% (antifreezing agent), deionized water added to 100% by weight.

Embodiment 3

[0034] Example 3: 50% Hexythiazox Fluazinam Suspension Concentrate

[0035] Formula: weigh hexythiazox 10.0%, fluazinam 40.0%, sodium lignosulfonate 3.5% (dispersant), sodium lauryl sulfate 3.2% (wetting agent), hydroxymethylcellulose 1.5% % (thickener), 0.2% silicone oil (defoamer), 2.5% ethylene glycol (antifreeze), and deionized water to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 18% hexythiazox·fluazinam suspension concentrate.

[0036] The preparation method of embodiment 1-3 is: take formula raw material according to quantity, mix, high-speed shearing disperse 30min, make the semi-finished product of suspending agent containing hexythiazox fluazinam after sand milling with sand mill, after packing, Just box it.

Abstract

The invention relates to a pesticide composition containing hexythiazox and fluazinam. The active ingredient is prepared from hexythiazox and fluazinam, and the weight ratio of hexythiazox to fluazinam is 1:(2-8). The two active ingredients of the pesticide composition synergistically interact to prevent and control citrus red mites; the pesticide combination can delay the development of pest resistance, reduce the application amount of each single agent, improve the control effect, and conform to the comprehensive management of pests.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing hexythiazox and fluazinam, which is used for preventing and controlling harmful mites in agriculture. Background technique [0002] At present, in the control of agricultural pest mites, due to the many generations of pest mites, rapid reproduction, and easy resistance, some acaricide varieties with good control effects, such as abamectin and pyridaben, have been used for many years. , the acaricide effect is significantly reduced or the effective control time of one application is very short, even for newly developed acaricides, if resistance prevention measures are not taken, resistance will usually develop quickly. By continuously increasing the frequency of use of pesticides and increasing the concentration of pesticides used, the ideal control effect cannot be achieved, and the cost of control and environmental pollution will also be increased. W...
