Abstract

The invention discloses a nicotine-farnesol compounded pesticidal composition, a preparation and application thereof. In the pesticidal composition containing an active component A and an active component B, nicotine is chosen as the active component A, farnesol is chosen as the active component B, and the weight ratio of the active component A to the active component B is 1:52 to 1:1. All the components of the composition disclosed by the invention come from plant sources, the composition can prevent and control a variety of pests, moreover, the composition has a remarkable synergistic effect, the pesticidal spectrum is broadened, and furthermore, the dosage of pesticide can be reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a nicotine and farnesol compound insecticidal composition, preparation and application thereof. The active ingredients of the composition of the invention are all derived from plant-derived substances. Background technique [0002] Finding and developing new aphidicides from natural resources has become one of the hot spots in the creation of new pesticides, and it is also the main way to seek alternatives to chemical pesticides. Although botanical pesticides have little environmental pollution and are safe for humans and animals, their efficacy is often inferior to that of chemically synthesized pesticides. For this reason, in the development of botanical pesticides, it is an important means to improve the practical application value of botanical pesticides through scientific compounding tests to obtain high-activity synergistic combinations. After research by the inventors, i...
