Embodiment Construction

[0007] Azadirachtin·scopolamine EC is prepared from the insecticidal active ingredients of azadirachtin and scopolamine, and then mixed with surfactants, synergists, stabilizers, sunscreen agents, preservatives, pH regulators, etc. Improve the retention and penetration of the medicament on crops and insects, thereby improving the control effect. The inventors used azadirachtin, hyoscyamine and other additives with different content combinations to carry out indoor toxicity test and field biological effect plot test on Pieris rapae larvae.

Abstract

Nimbin is extracted from nim kernel and has both pesticidal and bacteriostasis functions. Tropine is a kind of alkaloid extracted from solanaceae plant, such as henbane seed, belladonna and datura flower, and has powerful pesticidal function. Recompounding nimbin and tropine can obtain synergistic pesticidal effect. The nimbin-tropine emulsion of the present invention is recompounded with nimbin and tropine as main components and through adding proper amount of assistant. The pesticide has high efficiency, low toxicity, no pollution, safety to human body and farm animal and less resistance and may be used in preventing and treating various pests with resistance to other pesticides.

Description

Technical field [0001] The invention belongs to a mixed pesticide and relates to pesticide formulation and preparation technology. Background technique [0002] As humans rely on a single type of pesticides for a long time, pests are prone to become resistant to pesticides, leading to a sharp increase in the amount of chemical pesticides, which not only increase the economic burden of farmers, but also cause environmental and agricultural pollution. At present, there are a large number of mixed pesticides on the market. Insects, but most of them are mixed between chemical pesticides, which are highly toxic to humans and animals and easily cause pollution. Moreover, after long-term use, pests are also prone to resistance. Plant-derived pesticides come from nature, have good compatibility with the natural environment, have low toxicity, are not easy to cause pollution of the environment and agricultural products, and pests are not easy to develop resistance to pesticides. This is ...
