Embodiment 1

[0011] A slow-release high-efficiency biological insecticide, the raw material formula and weight percentage are: 30% L-α-amino acid ester, 5% patchouli essential oil, 5% Bacillus thuringiensis, 7% platycodon saponin, 6% emamectin benzoate, seaweed 10% sodium nitrate, 20% diflubenzuron, 2% dispersant, 15% rosin glyceride.

[0012] A preparation method of a slow-release high-efficiency biopesticide is:

[0013] (1) Mix L-α-amino acid ester, patchouli essential oil, Bacillus thuringiensis, platycodon saponin, emamectin benzoate, sodium alginate, diflubenzuron, dispersant, and rosin glyceride, and then granulate;

[0014] (2) Insert the insecticide particles into the pores of the stone powder expanded porous microbeads, and make the insecticide fill the pores of the porous microbeads by vacuuming and high pressure.

Embodiment 2

[0016] A slow-release high-efficiency biological insecticide, the raw material formula and weight percentage are: 15% L-α-amino acid ester, 10% patchouli essential oil, 10% Bacillus thuringiensis, 4% platycodon saponin, 2% emamectin benzoin, seaweed 12% sodium nitrate, 15% diflubenzuron, 6% dispersant, 26% rosin glyceride.

[0017] A kind of preparation method of slow-release high-efficiency biopesticide is the same as embodiment 1.

Abstract

The invention relates to a sustained-release efficient biological insecticide and a preparation method thereof. The insecticide is embedded into the pores of limestone-puffed porous microspheres, and the gaps of the porous microspheres are filled by the insecticide through vacuumizing and high pressure. The insecticide comprises the following raw materials in percentage by weight: 15-30% of L-alpha-amino acid ester, 5-10% of patchouli essential oil, 5-10% of bacillus thuringiensis, 4-7% of platycodin, 2-6% of emamectin benzoate, 10-12% of sodium alginate, 15-20% of chlorbenzuron, 2-6% of dispersing agent and 15-26% of rosin glycerol ester. The sustained-release efficient biological insecticide provided by the invention is not dissolved to be lost by the flowing water of soil in the gaps of the porous microspheres, thus residues and environmental pollution are avoided, the insecticidal effect is quick and obvious, and the sustained-release efficient biological insecticide is widely applicable.

Description

technical field [0001] The invention relates to an insecticide and a preparation method thereof, in particular to a slow-release high-efficiency biological insecticide and a preparation method thereof. Background technique [0002] The sustained-release effect of the present slow-release insecticide is not good, and the release amount of the insecticide is small. The release time is short and the duration of the drug effect is short, and it is easily dissolved and lost by the flowing water of the soil, and causes environmental pollution. Contents of the invention [0003] The object of the present invention is to provide a slow-release high-efficiency biopesticide and a preparation method thereof for the deficiencies of the prior art. [0004] The technical scheme adopted in the present invention is as follows: a slow-release high-efficiency biological insecticide, the raw material formula and weight percentage are: 15-30% of L-α-amino acid ester, 5-10% of patchouli essen...
