Embodiment 1
[0034] Formulation Example 1: 20% cyprofenac extract·Cyfluraniliprole suspension
[0035] Weigh out 100 grams of the extract from Tougucao, 100 grams of cyantraniliprole, 25 grams of polycarboxylate TERSPERSE 2700, 15 carats of open powder BX (sodium dibutyl naphthalene sulfonate), 15 grams of sulfonate Terwet 1004 , 20 grams of PVA (polyvinyl alcohol, molecular weight 2000), 5 grams of sodium carboxymethyl cellulose, 100 grams of kaolin, and 1000 grams of water. The above-mentioned raw materials are conventionally prepared by the method of preparing a suspending agent, that is, mixing, sanding with a sand mill to a particle size of less than 5 μm, and preparing an active ingredient content of 20% cytranlanprod.
Embodiment 2
[0036] Formulation Example 2: 40% Cytranylanprod 40% Extract
[0037] Weigh 100 grams of the extract of Tougucao, 300 grams of cyantraniliprole, 30 grams of agricultural milk 700#, 20 grams of agricultural milk 500#, 30 grams of agricultural milk 1601#, 80 grams of N-methylpyrrolidone, 50 grams of isocyanate The propanol is completely dissolved and mixed uniformly, deionized water is added to 1000 g, and after stirring, the effective ingredient content of 40% Cytranylantran extract is prepared.
Embodiment 3
[0038] Formulation Example 3: 35% Tetragus extract·fluoxaflor aqueous emulsion
[0039] Weigh 100 grams of the extract from Toluene, 250 grams of sulfoxaflor, 10 grams of agricultural milk 700#, 30 grams of agricultural milk 500#, 40 grams of agricultural milk 600#, 80 grams of toluene, 50 grams of isopropanol, 50 After dissolving gram of methanol completely and mixing uniformly, adding deionized water to 1000 grams, and stirring to prepare an active ingredient content of 35% Floxoxapyr extract·fluoxaflor aqueous emulsion.

Abstract
The invention discloses an agricultural pesticidal composition containing a tuberculate speranskia herb extract, and the agricultural pesticidal composition consists of a first active component and asecond active component, wherein the first active component is the tuberculate speranskia herb extract, and the second active component is cyhalodiamide or sulfoxaflor; and the weight ratio of the first active component to the second active component is 1:10 to 30:1. The agricultural pesticidal composition disclosed by the invention can be prepared into a suspending agent, aqueous emulsion and microemulsion which are agriculturally allowed to be used, and has a good prevention effect on rice stem borers, rice planthoppers, diamondback moths, beet armyworms, cabbage caterpillars, apple scale insects, apple aphids and cucumber aphids. According to the agricultural pesticidal composition containing the tuberculate speranskia herb extract disclosed by the invention, the problem that the prevention effect of tuberculate speranskia herb extract pesticides is not ideal is effectively solved, the dosage of cyhalodiamide or sulfoxaflor is reduced, the pressure on the environment is decreased, and the compounding of cyhalodiamide and sulfoxaflor has a remarkable synergistic effect and is safe for crops.
Description
Technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to an agricultural insecticidal composition, and in particular to an agricultural insecticidal composition containing an extract of Pseudomonas aeruginosa. The invention also provides the formulation and application of the insecticidal composition in agriculture. Background technique [0002] As people’s awareness of environmental protection and sustainable social development has increased, and the side effects of pesticides have been minimized, the development of biologically rational pesticides has become a consensus worldwide. 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. Moreover, with the increasing public demand for green food and pollution-free food, the market demand for plant-der...
