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 pesticide is a unique physical contact action on pests, the pest killing mechanism is to dissolve the wax layer 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 pesticide has a better control effect on citrus red spiders and scale insects.
Zingiber corallinum Hance is also called YINJIANG, and is a plant of Zingiber of Zingiberaceae, and is distributed in Guangdong, Hainan, Guizhou, Guangxi and Yunnan provinces in 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 controlling pests for one year and another year, the pest resistance is becoming serious and the species of pests producing resistance are increasing due to the increase of the usage 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 resistance to the D-limonene, and the prevention and control effect is 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.
