[0031] (1) Preparation of Herba Sperancifolia Extract

[0032] The extract of Speranthema fragrans described in this example can be prepared according to conventional methods, such as dipping extraction method, ultrasonic vibration extraction method and the like. In order to fully prepare the extract of Speranthemi fragrans, increase the yield of Sperancus fragrans extract, and shorten the time for preparing the fragrans fragrans extract. In this embodiment, it is preferable to use the method of combining immersion extraction and ultrasonic vibration extraction to prepare the extract of Speranthema fragrans.

[0033] It is best to use dried Sperancis fragrans, which is crushed and extracted by impregnating with organic solvents. There are various organic solvents available in this embodiment, such as methanol, ethanol, acetone, ethyl acetate, dichloromethane, chloroform or their mixed solvents.

[0034] As an optimal method for preparing the extract of Speranthema, specifica...

Embodiment 1

[0044] Take by weighing 250 grams of Sperantoides extract, 50 grams of tonpyradram, 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, and sand-milled by a sand mill until the particle size is less than 5 μm, and a suspending agent with an active ingredient content of 30% Sperantospermia extract·tofenpyramid is prepared.

Embodiment 2

[0046] Take by weighing 150 grams of Sperantosporum extract, 10 grams of emamectin, 25 grams of T36 (polycarboxylate), 30 grams of open powder BX (sodium dibutylnaphthalene sulfonate), 20 grams of K-12 (Sodium Lauryl Sulfate), 100 grams of Peronite, and 1000 grams of water. The above-mentioned raw materials are mixed through 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 16% Speranthema extract·emamectin suspending agent.

Abstract

The invention discloses an agricultural insecticide composition containing phryma leptostachya extractive, comprising a first active component and a second active component, wherein the mass ratio of the first active component to the second active component is 15:1-1: 5; the first active component is phryma leptostachya extractive, and the second active component is one of tolfenpyrad, methylamino abamectin, imidacloprid, chlorfenapyr, spirotetramat, buprofezin insecticides. The agricultural insecticide composition of the invention can be prepared to be suspending agent, emulsion in water and microemulsion allowed to use agriculturally, and has good preventive effects to brassicaceous vegetable plutella xylostella, cabbage caterpillar, apple scale insect, apple aphid, and cucumber aphid. The agricultural insecticide composition effectively solves the problem of not ideal prevention effect of phryma leptostachya extractive insecticide, reduces dosage of tolfenpyrad, methylamino abamectin, imidacloprid, chlorfenapyr, spirotetramat, buprofezin insecticides, and lighten environment pressure; the compound of the two components have obvious synergism and good crops safety.

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 Sperantosporum 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...
