Embodiment 1

[0032] Example 1 : Indoor Toxicity Determination of Veratrine and Liuyangmycin Compound on Tetranychus urticae

[0033] Test method: Using the glass slide dipping method, cut the double-sided tape into 2cm×2cm, stick it on one end of the glass slide, and gently stick the spider mite on the back of the bean leaf, so that the back of the spider mite sticks to the double-sided tape, Each chelicerae can move freely, put it at room temperature for 2 hours, observe with a dissecting microscope, strictly eliminate dead, inactive, insect state and inappropriate individual spider mites, and keep active nymphs as the test insect source. Completely dissolve the test agent with a small amount of acetone, dilute the agent to 5-6 mass concentrations on the basis of the preliminary test, and repeat each mass concentration 4 times, and clear water is used as the control. Immerse the mite-carrying glass slide in the liquid medicine, shake it lightly for 5 seconds, take it out, and quickly abs...

Embodiment 2

[0043] Example 2 : Field Control Effect of Veratrine and Liuyangmycin Compound on Tetranychus urticae

[0044] Test method: The test crop is kidney bean, and no chemical fertilizers or pesticides have been applied except for watering after emergence. The experiment was repeated 4 times. Mark 15 plants in each plot, investigate the base number of spider mites on each plant before spraying, start spraying after the survey is completed, the spraying liquid volume is about 450kg / hm2, investigate the number of surviving mites 10 days after spraying, and calculate the population decline rate and control effect.

[0045] Test drug:

[0046] potion 1 : 24% veratrine·liuyangmycin wettable powder (12% veratrine, 12% liuyangmycin, 3% sodium lignosulfonate, NNO5%, 1% stretch powder, kaolin to make up to 100%)

[0047] potion 2 : 36% veratrine·liuyangmycin EC (6% veratrine, 30% liuyangmycin, 10% N-methylpyrrolidone, 5% Nongru 400#, 3% epichlorohydrin, phenethylphenol Polyoxyethylene...

Abstract

The invention belongs to the technical field of researches and development of novel pesticides, and particularly relates to a veratrine containing insecticide composition. The veratrine containing insecticide composition comprises the effective ingredients of veratrine and Liuyang mycin, and the weight ratio of the veratrine to the Liuyang mycin is 1:40 to 40:1. The insecticide composition comprises the effective ingredients having different function mechanisms, the synergistic interaction is obvious, the use amount of a single dosage is reduced; the veratrine containing insecticide composition is active for all states of the pest mites and effectively slows down the production of resistance of the mites; and the composition adopts the biogenic pesticide, and the environment pollution is relatively low.

Description

technical field [0001] The invention belongs to the technical field of research and development of new pesticides, and in particular relates to an insecticidal composition containing veratrine. Background technique [0002] Mites, also known as red spiders, white spiders, etc., belong to Arthropoda Arachnida. The mites that mainly damage crops in agriculture mainly include spider mites such as Panonychus, Tetranychus cinnabarinus, and Tetranychus urticae, gall mites, and rust mites. These mites that damage crops usually have the characteristics of large number of eggs, fast reproduction, high population density, obvious generation overlap, and easy to produce drug resistance. It usually results in peeling of the fruit, chlorotic deformation of the leaves, malnutrition of the fruit tree, and finally devastating consequences such as falling flowers, leaves, and fruits. [0003] Veratrine is an active substance extracted from the rhizome of Veratrum, a perennial herb of the g...
