Embodiment 1

[0015] Example 1: Indoor Toxicity Determination of Carbosulfan, Pyriproxyfen and Their Mixtures to Citrus Yamushi

[0016] Test object: newly hatched nymphs of Unaspis yanonensis Kuwana.

[0017] Experimental design: Leaf dipping method was used. The effective lethal concentration ranges of carbufuran, pyriproxyfen and their mixtures with different ratios were determined through preliminary experiments. When the eggs of scale insects are in the peak hatching stage, select the leaves with more newly hatched nymphs of scale insects, soak them in the liquid medicine for 10 seconds, absorb the excess liquid medicine with absorbent paper, insert them into a small bottle with water, air dry, and mark them. Placed in an observation room at 25±1°C with 14 hours of light. Repeat 3 times, set up a blank control, check the results under a dissecting microscope after 24 hours, touch the worm body lightly with a brush, and if there is no response, it is regarded as a dead worm. The calc...

Embodiment 2

[0028] Embodiment 2: 8.0% carbofuran pyriproxyfen suspension concentrate

[0029] Formula: Take by weighing 6.0% of carbosulfan, 2.0% of pyriproxyfen, 2.5% of alkylphenol formaldehyde resin polyoxyethylene ether (dispersant), 3% of alkylphenol polyoxyethylene ether phosphate (moisturizing agent) Wetting agent), polyvinyl alcohol 1.5% (thickener), silicone 0.2% (defoamer), deionized water added 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 8.0% carbosulfan pyriproxyfen suspension concentrate.

Embodiment 3

[0030] Embodiment 3: 4.5% carbofuran pyriproxyfen suspension concentrate

[0031] Formula: Weigh 0.5% carbosulfan, 4.0% pyriproxyfen, 2.5% naphthalenesulfonate formaldehyde condensate (dispersant), 2.5% sodium lauryl sulfate (wetting agent), silicone Sodium 0.12% (defoamer), gum arabic (thickener) 0.12%, and deionized water are added 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 4.5% carbosulfan pyriproxyfen suspension concentrate.

Abstract

The invention relates to a composition containing benfuracarb and pyriproxyfen. Effective components consist of the benfuracarb and the pyriproxyfen in a weight ratio of (5 to 1) to (1 to 8). According to the composition, a synergistic effect is achieved by the two effective components, so that the pesticide effect can be enhanced greatly, the dosage of each single component is reduced, the pest resistance development can be delayed, and comprehensive treatment of pests is realized when the composition is used for preventing and controlling unaspis yanonensis kuwana.

Description

technical field [0001] The invention relates to the technical field of agricultural application, in particular to a composition containing carbofuran and pyriproxyfen, which is mainly used for preventing and treating citrus scale insects. Background technique [0002] There are many kinds of scale insects that harm citrus, such as Saccharomyces cerevisiae, red wax scale, and cotton scale, etc., and Scale sacrum is the most serious damage. The female adults and nymphs of the scorpion suck sap on the leaves, fruits and young shoots, forming macular spots on the damaged parts, resulting in deformed leaves, curling, dry branches and leaves, and the damaged parts of the fruits turn yellow-green, with poor appearance and sour fruit taste. Seriously affect tree vigor, yield and fruit quality, and can also induce bituminous coal disease. [0003] At present, there are many kinds of agents used to kill citrus scale insects on the market, but in some actual use processes, the effect ...
