Embodiment 1

[0017] Example 1: Indoor Toxicity Determination of Spinosyn, Phyllostachys and their Mixtures to Plutella xylostella

[0018] The test adopts the method of soaking leaves and inoculating insects: the test agent is made into a certain concentration of mother liquor, and then diluted with water to 5 gradient concentrations for use, and clean water is used as a control. Take fresh cabbage leaves and cut them into roughly 50 mm long pieces of the same size, soak the cut leaves in the prepared test drug solution for 10 seconds, take them out and let them dry naturally, then put them into the culture medium lined with filter paper in advance. In a dish (φ120mm). Then the 3rd instar larvae of Plutella xylostella were inserted into the dishes, 15 per dish, and each concentration was replicated three times. Place it in the greenhouse for cultivation, check and record the death situation after 72 hours, calculate the death rate, and obtain the regression equation of toxicity, correlati...

Embodiment 2

[0027] Example 2: 5.0% spinosyn·picillin suspension concentrate (spinosyn:picralin=3:2)

[0028] Weigh 3.0% of spinosad, 2.0% of picrodine, 3.5% of alkylaryl polyoxypropylene polyoxyethylene ether (dispersant), 5.0% of sodium polynaphthylsulfonate (wetting agent) , ethylene glycol 2.5% (antifreeze), xanthan gum 0.8%, silicone defoamer 0.3%, deionized water to make up to 100%.

[0029] The preparation method of Example 1-2 is: mix each component uniformly according to the ratio of the formula, after grinding and high-speed shearing, obtain an insecticidal composition containing pleosyn-pictericin, and the dosage form is a suspension .

Embodiment 3

[0030] Example 3: 4.0% spinosad · phasicine in water emulsion (spinosyn: piculin = 3: 1) Weigh 3.0% spinosyn and phasicine according to the amount 1.0%, 2% nonylphenol polyoxyethylene (EO=10) ether phosphate, 2% tristyrylphenol polyoxyethylene ether phosphate (Nongru 600# phosphate), xylene 10%, dodecane Calcium phenylsulfonate 3.5%, organic silicon 0.5%, water to make up to 100%.

Abstract

The invention relates to an insecticide composite containing celastrus angulatus and spinetoram. Effective components are composed of the spinetoram and the celastrus angulatus, wherein the weight ratio between the spinetoram and the celastrus angulatus is 2-5:1-2. The insecticide composite containing the celastrus angulatus and the spinetoram has the synergistic interaction, and when the insecticide composite containing the celastrus angulatus and the spinetoram is applied to prevention and control of plutella xylostella, development of the resistance of the plutella xylostella can be delayed, the application amount of each single agent can be reduced, and the prevention and control effects can be improved; and meanwhile, chemical pesticide residues can be reduced beneficially, and the requirement for comprehensive treatment of injurious insects can be met.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to an insecticidal composition containing picretin and spinosad. Background technique [0002] Plutella xylostella belongs to Lepidoptera Plutellaidae, and is an important resistant pest of cruciferous crops. The first instar larvae only eat the mesophyll, leaving the epidermis, forming transparent spots on the leaves, commonly known as "open skylights", 3 ~4th instar larvae can eat vegetable leaves into holes and nicks, and in severe cases, the whole leaf will be eaten into a net shape, resulting in deterioration of vegetable quality and serious economic losses. [0003] Spinetoram is a new type of botanical insecticide. Its English common name is Spinetoram. Spinetoram is produced from the fermentation of the actinomycete Saccharopolyspora spinosa. It is a spinosad (Spinasad) The derivative product, its mechanism of action is to act on the nicotinic acetylcholine re...
