Embodiment 1

[0014] Example 1: Indoor Toxicity Determination of Epoxycloprid, Pyriproxyfen and Their Mixtures to Citrus Yamushi

[0015] Test object: newly hatched nymphs of Unaspis yanonensis Kuwana.

[0016] Experimental design: Leaf dipping method was used. The effective lethal concentration ranges of cyclocloprid, pyriproxyfen and their mixtures in different proportions were determined through preliminary experiments. When the eggs of scale insects are in the peak hatching stage, select the leaves with many 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 vial with water, air dry, mark, and put 25 ± 1 ℃, 14h light observation room. 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 calculation formula is:

Embodiment 2

[0028] Embodiment 2: 8.0% epoxycloprid · pyriproxyfen suspension concentrate

[0029] Formula: take by weighing epoxycloprid 6.0%, pyriproxyfen 2.0%, alkylphenol formaldehyde resin polyoxyethylene ether 2.5% (dispersant), alkylphenol polyoxyethylene ether phosphate 3% (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% epoxycloprid pyriproxyfen suspension concentrate.

Embodiment 3

[0030] Embodiment 3: 5.5% epoxycloprid · pyriproxyfen suspension concentrate

[0031] Formula: Weigh 0.5% epoxycloprid, 5.0% pyriproxyfen, 2.5% naphthalenesulfonate formaldehyde condensate, 2.5% sodium lauryl sulfate, 0.12% silicones, 0.12% gum arabic, Ionized water is 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 a 5.5% epoxycloprid pyriproxyfen suspension concentrate.

Abstract

The invention relates to a method for preventing and controlling scale insects of oranges. The method comprises the following steps: mixing pesticide preparations containing epoxy thiacloprid and pyriproxyfen as active ingredients, mixing with water and then uniformly spraying onto orange plants till wetting the branches and leaves, wherein the weight ratio of epoxy thiacloprid and pyriproxyfen is(3:1)-(1:10). The two active ingredients in the invention have a synergic effect for preventing and controlling scale insects of oranges, the pesticide effect is greatly promoted, the active ingredient dosage is reduced, the adverse effect to environment and the pesticide residue are reduced and the control on the pest resistance to insecticide is benefited.

Description

technical field [0001] The invention relates to the technical field of agricultural application, in particular to a method for preventing and treating citrus scale insects. Background technique [0002] There are many kinds of citrus scale insects that harm citrus scale insects, such as scorpion scorpion, red wax scale, and cotton scale, etc., and scorpion scorpion 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 medicaments for killing citrus scale insects on the market, but in some actual use processes, the effect is always unsatisfactory. For example, the...
