Problems solved by technology

However, the use of spirotetramat and lambda-cyhalothrin for the control of apple aphid has not been reported, and the pests and compositions prevented and killed in the prior art do not have the specific control of apple aphid. There is no strict joint virulence test results for the apple aphid and no evaluation of the actual application control effect on the apple aphid by field application.

Embodiment 1

[0045] The purpose of this example is to study the synergistic effect of the mixed use of spirotetramat and lambda-cyhalothrin on the cotton aphid.

[0046] The indoor toxicity of the tested pesticides to the adult aphids of the apple cotton aphid was dipped. Dilute the mother liquors of each agent with an aqueous solution containing 0.1% Tween 80 to form 4 to 6 series of mass concentrations in an equiproportional gradient. Distilled water containing 0.1% Tween 80 and 0.1% acetone was used as blank control. Pick adult apple aphids of the same size and put them into a funnel folded from filter paper, use a dropper to suck up the liquid medicine and drop it into the filter paper funnel, stick the bottom of the funnel on the wall of the glass vessel, and let the medicine liquid in the funnel flow out naturally ( 10 seconds), put the treated cotton aphid on the dry filter paper, gently pick the cotton aphid into the plastic box with a brush, put the leaves in the box and keep it mo...

Embodiment 2

[0056] The purpose of this example is to study the synergistic effect of spirotetramat, lambda-cyhalothrin and different compositions on the cotton aphid.

[0057] The indoor toxicity of the tested pesticides to the adult aphids of the apple cotton aphid was dipped. The mother solutions of each agent were diluted with an aqueous solution containing 0.1% Tween 80 to the concentration to be tested. Distilled water containing 0.1% Tween 80 and 0.1% acetone was used as blank control. Pick adult apple aphids of the same size and put them into a funnel folded from filter paper, use a dropper to suck up the liquid medicine and drop it into the filter paper funnel, stick the bottom of the funnel on the wall of the glass vessel, and let the medicine liquid in the funnel flow out naturally ( 10 seconds), put the treated cotton aphid on the dry filter paper, gently pick the cotton aphid into the plastic box with a brush, put the leaves in the box and keep it moist, and cover it with a b...

Embodiment 3

[0062] The purpose of this experimental example is to study the efficacy test of 30% (spirotetramat + lambda-cyhalothrin) suspension in the control of apple cotton aphid.

[0063] Before the test, self-prepared 30% (spirotetramat + lambda-cyhalothrin, weight ratio of 9:1) suspension concentrate, 30% (spirotetramat + lambda-cyhalothrin, weight ratio of 15:1) ) suspension for testing. In the test, 30% (spirotetramat + lambda-cyhalothrin, 9:1) SC and 30% spirotetramat + lambda-cyhalothrin (15:1) SC were used respectively. The active ingredient dosage was 100 mg / L and 50mg / L treatment, and 22.4% spirotetramat SC active ingredient dosage 200mg / L and 2.5% lambda-cyhalothrin EC active ingredient dosage 12.5mg / L were treated as control agents. During the test, each test agent was diluted with water and then sprayed. Two trees were used for each treatment, and 15 points were investigated for each tree. The application period is September, and the average amount of drug solution per...

Abstract

The invention relates to a pesticidal composition containing spirotetramat and lambda-cyhalothrin and application thereof in preventing and treating woolling aphis. The pesticidal composition comprises the following components in parts by weight: 10.0-40.0 parts of spirotetramat and 1.0-5.0 parts of lambda-cyhalothrin. The pesticidal composition containing spirotetramat and lambda-cyhalothrin can fully display the respective advantages of the spirotetramat and lambda-cyhalothrin, and can be used for preventing and treating woolling aphis; and the composition of the two effective components has an obvious synergistic action, can achieve the effects of enhancing the preventing and treating effects and postponing the drug effect, has the advantages of quick effect taking and long duration, and is superior to the prior art. The composition can reduce the pesticide consumption, lower the cost and alleviate the environmental pressure.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to the application of an insecticidal composition containing spirotetramat and lambda-cyhalothrin in the control of apple cotton aphid. Background technique [0002] The apple cotton aphid, Eriosoma lanigeru Hausmann, belongs to the order Homoptera, and is a worldwide quarantine pest. 1. Originated in the eastern part of North America, it was first discovered in the United States, and later spread to Europe, Australia, and Asia, Japan, Korea, India and other countries. It occurs in about 70 countries and regions on six continents in the world. It occurs in some provinces of my country. Invasive species that cause serious harm to my country's agricultural production. [0003] The insect reproduces quickly and has a strong latent capacity. It gathers on the host's new shoots, side branches, trunks, roots, and pruning mouths to absorb juice, weakening the tree vigor, and can cause 4.1% to 38.8...
