Problems solved by technology

The review of the existing literature shows that the intercropping of wheat in the orchard can repel the black velvet beetle, but because the saplings of the fruit trees require a lot of fertilizer and water, the intercropping of wheat will not only affect the growth of the saplings of the fruit trees, but also affect the field of the orchard. operate
Further searches showed that there were no research reports on the repellence of wheat straw extracts to the black velvet beetle, and no related patents were published

Embodiment

[0024] Preparation of 15% Wheat Straw Extract Emulsion in Water:

[0025] Accurately weigh 15g (mass percentage is 15%), dissolve the freeze-dried powder of wheat straw extract in solvent (ethanol), and then add 10-15% Tween 80, fatty alcohol polyoxyethylene ether, aralkylphenol polyoxyethylene Oxyethylene ether and ethylene oxide propylene oxide copolymer are used as emulsifiers to form an oil phase, and then 2% of polyethylene glycol is added as a stabilizer, 1% of emulsified silicone oil is used as a defoamer, 0.5% of silicon Aluminum magnesium acid and 0.2% xanthan gum are mixed to form an aqueous phase. Add the water phase to the oil phase under the agitation of a high-speed shearing machine at 3500-4500r / min, and emulsify with high-speed shearing for 10 minutes to form a well-dispersed water emulsion.

Abstract

The invention discloses a botanical repellent for the black velvet beetle and a preparation method thereof. The botanical repellent is prepared from the following raw materials in mass percentages: wheat straw ethanol extraction dry powder 1-45%, solvent 10% ~30%, emulsifier 5~10%, defoamer 0.1~1.5%, other additives 0.3~5%, and the balance is water. The preparation of the present invention is an emulsion in water, the amount of organic solvent is less, and it is environmentally friendly. It is a pollution-free botanical pesticide with easy-to-obtain raw materials, abundant resources, low cost, turning waste into treasure, and comprehensively utilizing wheat straw resources; The invention has lower requirements on processing equipment, simple processing technology and good promotion prospect. The invention can be used for the repelling control of fruit trees and wood chafers. High repellent activity, friendly to the environment, not easy to produce resistance and so on.

Description

technical field [0001] The invention relates to the field of botanical pesticides, in particular to a botanical repellant for the black velvet beetle and a preparation method thereof. Background technique [0002] Black velvet beetles, also known as velvet beetles, oriental beetles, and black velvet beetles, belong to Coleoptera and Beetleidae. It is a multi-host pest that feeds on most fruit tree varieties in northern my country, such as apples, pears, cherries, hawthorns, peaches, etc. . It mainly feeds on the young leaves and shoots of fruit trees with adults, and it is more harmful in newly developed orchards, especially in the North China Plain and the Loess Plateau, and often causes serious harm to young trees. Our preliminary survey found that in the newly developed apple orchards, pear orchards and cherry orchards in the plains of Shandong, the Luliang Mountains of Shanxi, and the gully areas of the Loess Plateau, the black velvety beetle caused 80-100% damage to the...
