Abstract

The invention discloses a plant-derived preparation for controlling whitefly pests and a preparation method thereof. The preparation method comprises the following steps: mixing manchurian wildginger whole plants, thorn apple and kusnezoff monkshood root tuber according to the weight ratio of 1: 1: 1, processing and breaking into particles by using a crushing machine, screening by a 60-mesh screen, placing 20kg of particles into an extraction kettle of a traditional Chinese medicine multifunctional extraction device for extraction, adding 75 liters of 75% ethanol, steaming and boiling for 2.0hours at the temperature of 82-85 DEG C, and then concentrating for 1hour to obtain a composite extract concentrated cream and a crystal of the wildginger whole plants, thorn apple and kusnezoff monkshood root tuber; further adding 75% ethanol solvent, fully dissolving to prepare a saturated solution, bottling and sealing to prepare the preparation. Test results show that the plant-derived preparation for controlling the whitefly pests has not only a higher control effect against the whitefly pests, but also the advantages of no environmental pollution, low cost, simple manufacturing process, cost-saving property, safety, directness, environment-friendly property and high efficiency.

Description

technical field [0001] The invention relates to the field of agricultural prevention and control, in particular to a plant source preparation for preventing whitefly pests and a preparation method thereof. Background technique [0002] Whitefly pests refer to the piercing-sucking insects of the Homoptera Whitefly superfamily. Adults of both sexes have wings, and the body and wings are covered with white wax powder. Whitefly pests widely occur on various crops such as grain, oil, vegetables, and fruit trees. The damage is quite common, and the losses caused are very serious, and its control is relatively difficult. It is listed as a major worldwide pest and can be called a plant pest. The stubborn disease in the disease has been paid more and more attention. [0003] my country's plant resources are very rich, and nearly a thousand species of plants contain insecticidal substances, which are important resources for the development of plant-derived insecticides. Since the ac...
