Problems solved by technology

[0002] Traditional tobacco storage uses fumigation methods for pest control, mainly aluminum phosphide and methyl bromide for warehouse fumigation. With the increase of resistance of storage pests to fumigants, the fumigation effect is reduced; the damage to tobacco and equipment during the fumigation process, loss of personnel, etc.

example

[0032] The designed S-methoprene product and similar juvenile killing products on the market were tested for killing tobacco beetle eggs. The prepared S-methoprene agent was carried out with the same effective concentration of 5ppm and 10ppm as the market-purchased juvenile agents to carry out the control disinfecting experiment. The specific steps are as follows:

[0033] First, the same effective concentration of larvicide was evenly sprayed on the tobacco sheets through spraying equipment; then the same number of tobacco beetle eggs were sprayed on the smoke sheets sprayed with different agents to observe the survival rate (%) of tobacco beetle eggs.

[0034] The above-mentioned test is to put 50g of smoke sheets in a closed but air-permeable container. The spraying amount of the medicament containing S-methoprene of the present invention and a certain similar juvenile killing product are based on the effective ingredients contained in the smoke sheets being 5ppm and 10ppm. ...

Abstract

The invention relates to a biological insecticide containing Sinotefuran, as well as the preparation and application methods thereof. The biological insecticide containing Sinotefuran is characterizedby comprising the following components in percentage by mass: 0.5% of Sinotefuran, 0.5% of an antioxidant, 0.7% of an ultraviolet protective agent, 12.8% of a surfactant, 39.8% of an ethanol solventand 45.7% of deionized water. The invention provides the biological insecticide containing the Scenthoxystrobin and used for tobacco planting and storage, which is good in dispersity, relatively stable, good in solubility, good in insecticidal effect, non-toxic and simple in preparation method.

Description

technical field [0001] The invention relates to the technical field of biopesticides, in particular to a biopesticide containing S-methoprene and its preparation and application method. Background technique [0002] Traditional tobacco storage uses fumigation methods for pest control, mainly aluminum phosphide and methyl bromide for warehouse fumigation. With the increase of resistance of storage pests to fumigants, the fumigation effect is reduced; the damage to tobacco and equipment during the fumigation process, loss of personnel, etc. Aluminum phosphide is slowly withdrawing from the market, and the country is currently looking for effective alternatives to fumigation and insecticide in tobacco. Contents of the invention [0003] The object of the present invention is to provide a tobacco biopesticide containing S-methoprene with good dispersibility, relative stability, good solubility, good insecticidal effect, non-toxicity and simple preparation method. [0004] In...
