Description
Technical Field
The invention belongs to the field of pesticides, and particularly relates to a synergistic auxiliary composition for a D-limonene soluble solution.
Background
D-limonene (D-limonene) is orange oil extracted from orange peels by a professional cold pressing technology, and belongs to natural plant source pesticides. The action mode of the insecticide on pests is a unique physical contact action, the insecticidal mechanism is to dissolve the wax coat on the body surface of the pests, so that the pests are quickly knocked down and die in an obvious water loss state, and the insecticide has a good control effect on citrus red spiders and scale insects.
Zingiber corallinum Hance, also known as YINJIANG, is a plant of Zingiber of Zingiberaceae and is distributed in Guangdong, hainan, guizhou, guangxi and Yunnan of China. The rhizome is used as a medicine, has warm and pungent nature and flavor, enters lung, stomach and spleen channels, and has the effects of warming middle-jiao to dispel cold, reducing swelling, detoxifying, resisting bacteria, relieving itching, eliminating phlegm and the like. The Zingiber corallinum Hance contains various active substances, especially Zingiber corallinum Hance essential oil, has various biological activities such as antibacterial property, oxidation resistance and the like, is applied to the fields of medicines and cosmetics, and no research report on the aspect of plant insecticidal synergy is discovered at present.
The problem of resistance to agricultural pests is a global problem and has always been a key issue of concern for agricultural scientists. With the continuous use of pesticides for preventing and controlling pests for one year or another, the resistance of pests is becoming more serious and the variety of pests producing resistance is increasing due to the increase of the use amount of pesticides and unscientific use of pesticides and other factors. In the citrus planting area, the D-limonene is singly used for preventing and controlling citrus red spiders and scale insects in a long-term transition manner, so that pests have greater drug resistance to the D-limonene, and the prevention and control effects are increasingly poor. Therefore, a stable, efficient, low-toxicity and environment-friendly synergistic additive needs to be researched to improve the pest control effect of the D-limonene, prolong the service life of the D-limonene, reduce the dosage, save the cost and reduce the pollution to the environment.
