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, 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...
