Problems solved by technology

[0002] Now in the prevention and control of agricultural diseases and insect pests, the pesticide residue problem caused by the extensive use of traditional chemical pesticides will also cause the accumulation of their toxicity in the ecosystem, which not only pollutes the environment, but also causes harm to organisms at all levels, seriously affecting the ecological balance. destroy
In actual production, there are even cases of using highly toxic and highly toxic pesticides in order to achieve the effect of the rule of law, which has brought huge harm to the society.
[0003] At present, some biological source pesticides have also appeared on the market, but due to many factors such as single ingredients, poor control effect, and short duration, it is difficult to promote them in practical applications.

Embodiment 1

[0023] Raw materials and weight percentage: 0.5% matrine, 5% guanzhong extract, 1% rotenone, 2000 IU / mg Bacillus thuringiensis, 0.6% abamectin, 0.3% emamectin benzoate, 8% calcium lignosulfonate, wood Sodium Sulfonate 5%, Kaolin Clay Top Up 100%.

[0024] The above raw materials are uniformly mixed, pulverized by a jet mill, and processed into a wettable powder. details as follows:

[0025] (1) Accurately weigh the above raw materials, put them into the mixing mixer one by one, and stir for half an hour.

[0026] (2) Slowly feed the mixed materials into the crushing system of the jet mill, adjust the air pressure at 8-10 kg, and adjust the classifying wheel to make the output meet the fineness requirements.

[0027] (3) The discharged material is collected by the cyclone separator, and the exhaust gas is processed by the trap.

[0028] (4) After the crushing is completed, collect all the discharged materials and pack them.

[0029] Control experiment of experimental example 1 to cotton bollworm

[0030] 1. Objects and methods

[0031] 1.1 Target: Cotton planting base in Liudian Village, Guoziwa Township, Hejian City, Hebei Province

[0032] 1.2 Method: Take blank as control, 5% emamectin benzoate WP (self-made) 10g / mu as contrast, the wettable powder obtained in embodiment 1 20g / mu, adopt random block arrangement, and separate zones are set up between the cells. 30 kg of water per mu, sprayed once with a single-head sprayer.

[0033] 2. Results: 3 days, 5 days, and 9 days after the spraying, 10 cotton plants in each plot were selected to investigate the base number of insects, and finally the control effect of the plot was calculated. At the same time, the growth of cotton leaves was observed to verify the safety of the pesticides on the crops.

Embodiment 2

[0037] Raw material and weight percentage: Matrine 1%, Guanzhong Extract 3%, Rotenone 1.2%, Bacillus thuringiensis 1000IU / mg, Abamectin 1%, Emamectin 0.5%, LB-19C 4%, LB-52D 1%, Xanthan Gum 0.2%, Potassium Sorbate 0.2%, Ethylene Glycol 5%, SAG-630 0.3%, Water Make Up 100%.

[0038] The above raw materials are uniformly mixed in a stirring tank, sanded by a sand mill, and processed into a suspending agent. details as follows:

[0039] (1) Accurately weigh the above-mentioned raw materials, first add water in the stirring tank, then add surfactant, xanthan gum, preservative, ethylene glycol, antifoaming agent successively while stirring, and finally slowly add the former drug (bitter ginseng, guanzhong extract, rotenone, Bacillus thuringiensis, abamectin and emamectin benzoate), stir well.

[0040] (2) Slowly pass the uniformly stirred material through four series-connected sand mills for sand grinding, turn on the cooling circulating water, adjust the feeding speed, and make ...

Abstract

The invention relates to the technical field of pesticide compounding and particularly discloses an insecticidal composition including plant-sourced pesticides. The insecticidal composition includes bacillus thuringiensis by 100 million to 10 billion living spores per gram, and active components including, by weight, 0.1-5 parts of sophocarpidine, 0.1-5 parts of extract of cyrtomium fortunei, 0.1-5 parts of rotenone, 0.1-5 parts of avermectins and 0.1-5 parts of emamectin benzoate. The invention is direct at problems that a bio-sourced pesticide only has single component, is poor in prevention and control effect and is short in lasting period. In a large quantity of scientific experiments, plant-sourced pesticides, microbial-sourced pesticides and high-effective low-toxic chemical pesticides are compounded and processed to produce dose forms such as wettable powders, powders, suspensions, dispersible granules, etc. The insecticidal composition has wide insecticidal spectrum and quick and good effects and the active components are easy to degrade.
