[0027] (1) Preparation of bark root bark extract

[0028] After the root bark of the willow bark is pulverized, it is extracted with an organic solvent under heat reflux for three times, and the extracts are combined. The selected organic solvent can be alcohols (such as methanol, ethanol, etc.), ketones (such as acetone, etc.), ethers (such as ether, etc.). For the present invention, ethanol can be used to extract the root bark of the willow bark, the heat reflux extraction time is 6 hours, the heating extraction temperature is set to 70°C, the extracts are combined for 3 times, and the root bark of the bark bark is obtained after the solvent is removed by a rotary evaporator , and the yield was 7.3-8.9%.

[0029] (2) preparation preparation part

[0030] The agricultural insecticidal composition of the present invention, the first component is the bark root bark extract of the willow that can be prepared by the above method, and the second component is selected from tonami...

Embodiment 1

[0036] Take by weighing 250 grams of willow root bark extract, 50 grams of pyrenpyrrole, 50 grams of sodium lignosulfonate, 20 grams of open powder BX (sodium dibutylnaphthalene sulfonate), 30 grams of K-12 (dodecyl sodium sulfate), 20 grams of PVA (polyvinyl alcohol, molecular weight 2000), 20 grams of polyvinylpyrrolidone, 100 grams of kaolin, and 1000 grams of water. The above-mentioned raw materials are mixed by a conventional method for preparing a suspending agent, sand-milled with a sand mill until the particle size is less than 5 μm, and the active ingredient content is 30% of the active ingredient content of willow root bark extract · pyrenpyramid suspending agent.

Embodiment 2

[0038] Take by weighing 250 gram bark willow root bark extract, 50 gram spinosad, 25 gram T36 (polycarboxylate), 30 carats open powder BX (sodium dibutylnaphthalene sulfonate), 20 gram K-12 (12 sodium alkyl sulfate), 100 grams of bentonite, and 1000 grams of water. The above-mentioned raw materials are mixed by a conventional method for preparing a suspending agent, and sand-milled by a sand mill until the particle size is less than 5 μm, and the active ingredient content is 30% of the root bark extract of the bark willow spinosad.

Abstract

The invention discloses an agricultural insecticide composition containing a periploca sepium bunge root and bark extract; the agricultural insecticide composition includes the first active ingredient periploca sepium bunge root and bark extract, and the periploca sepium bunge root and bark extract is prepared from the following method: crushing periploca sepium bunge roots and barks, carrying out heat reflux extraction with an organic solvent, removing the solvent of the extract, and thus obtaining the extract. The composition also includes a second active ingredient which is one of tolfenpxrad, spinosad, chlorantraniliprole, buprofezin, spirotetramat, flonicamid and pyriproxyfen. The weight ratio of the first active ingredient to the second active ingredient is 15:1-1:5. The composition can be made into a suspending agent, an emulsion in water and a microemulsion, and has relatively good control effect on cruciferous vegetable diamondback moth, cabbage caterpillar, apple scale insect, apple aphid, cucumber aphid, tomato bemisia tabaci and cucumber whitefly. The composition can effectively solve the problem that the control effect of the periploca sepium bunge root and bark extract is not ideal, reduces the dosage of chemical pesticides, and alleviates the pressure on the environment; and compounding of the two ingredients has remarkable synergistic effect and has good safety to crops.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to an agricultural insecticidal composition, in particular to an agricultural insecticidal composition containing bark root bark extract. The invention also provides the formulation and application of the insecticidal composition in agriculture. Background technique [0002] With the enhancement of people's awareness of environmental protection and social sustainable development, it has become a worldwide consensus to minimize the side effects of pesticides and to develop biologically rational pesticides. Botanical pesticides have the advantages of low toxicity, low residue, basically harmless to non-target organisms, and no pollution to the environment. The development and application of botanical pesticides has gradually become a trend. And as the public's demand for green food and pollution-free food is increasing, the market's demand for botanical pesticides is also i...
