Problems solved by technology

Though play certain control effect, there are many disadvantages: (1) for improving drug effect, spraying dosage is bigger, but spray control has more than 90% medicament to drop in soil or float in the air and lose, The phenomenon of drug waste and environmental pollution is serious; (2) single application and large amount of pesticides are easy to produce drug resistance; (3) the hatching nodes of larvae are not uniform, the hatching time is long, and the control effect of each agent is not good due to short persistence

Embodiment 1

[0025] The present embodiment relates to a smear for the prevention and treatment of C. jujuba, prepared from the following raw materials by weight:

[0026] 1.6 parts of quicklime powder, 3 parts of sulfur powder, 26 parts of cottonseed oil.

[0027] The particle sizes of the quicklime powder and the sulfur powder are both smaller than 325 meshes.

[0028] The present embodiment also relates to the preparation method of this smear, comprising the following steps:

[0029] The vegetable oil is heated to 120° C. under pressure, and then the sulfur powder is added. After it is fully dissolved, the quicklime powder is added, and the reaction is performed for 15 minutes while maintaining a constant temperature.

Embodiment 2

[0031] The present embodiment relates to a smear for the prevention and treatment of C. jujuba, prepared from the following raw materials by weight:

[0032] 2 parts of quicklime powder, 5 parts of sulfur powder, 30 parts of rapeseed oil.

[0033] The particle sizes of the quicklime powder and the sulfur powder are both smaller than 325 meshes.

[0034] The present embodiment also relates to the preparation method of this smear, comprising the following steps:

[0035] The vegetable oil is heated to 115° C. under pressure, and then the sulfur powder is added. After it is fully dissolved, the quicklime powder is added, and the reaction is performed for 20 minutes while maintaining a constant temperature.

Embodiment 3

[0037] The present embodiment relates to a smear for the prevention and treatment of C. jujuba, prepared from the following raw materials by weight:

[0038] 1 part of quicklime powder, 2 parts of sulfur powder, 20 parts of soybean oil.

[0039] The particle sizes of the quicklime powder and the sulfur powder are both smaller than 325 meshes.

[0040] The present embodiment also relates to the preparation method of this smear, comprising the following steps:

[0041] The vegetable oil is heated to 130° C., and then the sulfur powder is added. After it is fully dissolved, the quicklime powder is added, and the reaction is carried out for 15 minutes under the condition of maintaining a constant temperature.

Abstract

The invention relates to a smearing agent for preventing Eulecanium gigantean, the smearing agent is prepared from the following raw materials by weight: 1-2 parts of quicklime, 2-5 parts of sulphur powder and 20-30 parts of vegetable oil. A medium of the smearing agent is the vegetable oil, the smearing agent is not applied in the form of spray, and drug waste is small. Compared with water, the vegetable oil has strong permeability to waxy shell and is not volatile. An active ingredient is dispersed in the vegetable oil to reduce contact with air, so that the lasting period is long. In a growth cycle of the Eulecanium gigantean, the smearing agent can be applied only once. In the prior art, again spraying in the first ten days of June and spraying for multiple times in the later stage canbe omitted, the smearing agent is time and effort-saving, non-polluting to the environment, and less in toxicity to crops. Moreover, compared with the existing compound insecticides with a single sterilization principle, insecticidal mechanisms of the quicklime and the sulfur powder are more complicated, drug resistance is not easy to cause, and the smearing agent can be used for a long time.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a smear for preventing and treating Coccus jujuba and a preparation method thereof. Background technique [0002] Eulecanium gigantean (scientific name: Eulecanium gigantean) is also known as Eulecanium gigantean. It belongs to the Homoptera Scale family, and it mainly harms pears, jujubes, sour jujubes, persimmons, walnuts, apples, mountain stamens, peach, locust, thorn roses, etc., and is an agricultural pest. The jujube coccus is mainly harmed by female adults and nymphs fixed on branches and sucking sap. After overwintering, the nymphs and adults gather on the branches and suck the sap, which damages the transport tissue of the cortex, leads to weak growth of the tree, and directly affects the yield and quality of the fruit. In severe cases, the branches may die or even the entire plant will die. The worm occurs once a year in the northern region. The 2nd instar nymph can crawl a...
