Novel use of fraxinellone and fraxinellone aqua pesticide

Abstract

The invention relates to a novel usage of fraxinellon and an insecticide of water aqua of fraxinellon, in particular to the application of fraxinellon in preparing the insecticide. The insecticide in the invention is a solvent extract of a root bark of Dictamnus dasycarpus Turcz. The insecticide of water aqua of fraxinellon in the invention is an insecticide of water aqua made with fraxinellon as an active component, which is prepared by the raw materials with a weight percentage as: 7 to 8 percent of fraxinellon, 10 to 13 percent of emulsifier, 15 to 20 percent of solvent the rest is water. The invention is of high effect, low toxicity, pollution-free and is easy to degrade and compatible with the environment. Through the experiment in large fields, the 75G/L insecticide of water aqua of fraxinellon has a certain prevention effect on the diamondback moth, while the prevention effects of the liquids with 200 times, 300 times and 500 times of the 75G/L insecticide of water aqua of fraxinellon are respectively 65.46 percent, 61.45 percent and 54.55 percent. The drug effects are increased by a certain extent after being controlled for seven days which respectively reach 70.42 percent, 64.50 percent and 59.70 percent.

Description

technical field [0001] The invention relates to a new application of arketone and an arketone aqueous insecticide. Background technique [0002] The inherent disadvantages of chemical pesticides and people's irrational long-term abuse, their toxic side effects and negative impact on the environment and ecological balance are beyond doubt. With people's understanding of pesticides and the emergence of toxic and side effects of chemical pesticides on humans, animals and the environment, natural plant-derived pesticides are favored by people. [0003] Among the nearly 30,000 species of higher plants in my country, nearly a thousand plants have insecticidal activity. The active ingredients of these plants not only have good insecticidal effect, are safe and easy to degrade crops, have a short residual effect period, and are not easy to produce drug resistance. As a plant source Pesticides have broad prospects. However, only 10% of people have studied their chemical properties, a...

Alkaloids are generally considered to be active chemical components, but the biological activities of Limonoids (limonoids) and Degraded limonoids (degradable limonoids) contained in Rutaceae and Meliaceae plants have aroused people's attention. Widely concerned, Fraxinellone isolated from neem bark is a Degradedlimonoids, its biological activity has been reported, but there is no research on the preparation of Fraxinellone obtained from white moss bark into botanical pesticides
