Problems solved by technology

It is precisely because of the large occurrence of melon aphids, unreasonable use of drugs in the field, and the short life cycle of generations, which directly lead to the rapid development of drug resistance of melon aphids. At present, it has become one of the main pests with serious drug resistance and difficult to control.
[0006] In the actual process of agricultural production, the use of chemical agents is the most effective means of controlling crop pests, but the most likely problem caused by chemical control of pests is the emergence of pest resistance
Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution.

Embodiment 1

[0020] Example 1: Screening of the compound ratio of sulfoxaflor and veratrine on the melon aphid and determination of co-toxicity coefficient

[0021] 1.1 Pests tested

[0022] Inoculate the melon aphid adults raised on cucumbers in the greenhouse to cucumber seedlings that have grown to 2 to 3 unfolded leaves without insects. After the nymphs are produced, remove the adults in time, and place the cucumber seedlings at ambient temperature in a constant temperature incubator at 25°C. Wait until it develops to 2 instar nymphs as stand-by.

[0023] 1.2 Drugs to be tested: 1% veratrine mother solution (purchased in conventional market); 96% sulfoxaflor technical substance (purchased in conventional market).

[0024] 1.3 Determination of the toxicity of sulfoxaflor and veratrine to the melon aphid

[0025] The drop method is used for determination, and the details are as follows: first, the micro dropper is cleaned with a solvent, and the dropper is adjusted to a standby state....

Embodiment 2

[0035] Embodiment 2: Field efficacy test of controlling cucumber melon aphid

[0036] This embodiment is used to prevent and control cucumber melon aphids. Before the application of the pesticide, the population base of the insects is investigated, and the number of residual living insects is investigated respectively on 1d, 3d, 7d, and 14d after the application of the pesticide. During the investigation, each plot is carried out according to the diagonal 5-point sampling method. For the remaining aphids on 2 cucumber plants, record the number of live insects and calculate the control effect. The anti-efficiency calculation method is as follows:

[0037]Control effect (%)=(1-CK1×Pt1 / CK2×Pt2)×100.

[0038] Among them: CK1 represents the number of insect populations before treatment in the control area; Pt1 represents the number of insect populations after treatment in the treatment area; CK2 represents the number of insect populations in the control area after treatment; Pt2 r...

Abstract

The invention discloses an insecticidal composition containing veratridine and sulfoxaflor. The active components of the insecticidal composition are veratridine and sulfoxaflor, wherein a mass ratio of sulfoxaflor to veratridine is 50-1: 1, preferably 20-1: 1, most preferably 20: 1 or 2: 1. The insecticidal composition containing veratridine and sulfoxaflor in the invention can effectively prevent and treat various pests with piercing-sucking mouthparts, e.g., Aphididae, Aleyrodidae, Cicadellidae, Delphacidae and Thripidae pests, and the insecticidal composition has particularly high active to Aphididae pests; and the insecticidal composition suitable for is applicable to plants like vegetables, ornamental plants, fruit trees and citrus and to a variety of field crops like rice, cotton, wheat and corn. The insecticidal composition containing veratridine and sulfoxaflor in the invention has obviously higher insecticidal effect compared with conventional single-component preparations, and is long in action period, safe to crops and worth promotion in agricultural production.

Description

technical field [0001] The invention relates to an insecticidal composition containing veratrine and sulfoxaflor, and its application in pest control, belonging to the technical field of pest biological control. Background technique [0002] During the growth process, crops are often harmed by various pests, especially vegetables and fruit trees. There are many kinds of pests and serious damage, such as aphids, whitefly, diamondback moth, cabbage caterpillar, beet armyworm, Spodoptera litura, cotton bollworm, leaf roller moth, scale insects, and harmful mites. In the process of pest control, chemical pesticide control is the main control method for crop pests, but long-term use will increase the resistance of pests year by year, and the control effect will decline, and the frequent use of chemical pesticides will also damage the ecological environment and threaten human health. Biopesticides are currently the hotspots of research, but compared with chemical pesticides, a bi...
