Plant insect expelling and killing smoking agent and use method thereof

Abstract

The invention relates to a plant insect expelling and killing smoking agent and a use method thereof. The preparation method comprises: screening 50% by weight of dry sawdust, 3% by weight of carbon powder, 43% by weight of mirabilis himalaica whole plant powder, 3% by weight of hydroxyethyl cellulose and 1% by weight of corn starch through a 40-mesh sieve for standby application; adding clear water accounting for the weight of a all-component smoking agent into all the raw materials excluding hydroxyethyl cellulose, uniformly stirring, respectively adding commercially available aspergillus niger and trichoderma according to 1/1500 of the weight of the all-component smoking agent to prepare a fermentation material, putting the fermentation material into a foam box, controlling the temperature to be 60 DEG C, performing high-temperature fermentation for 6-7 days, adding a hydroxyethyl cellulose solution into the fermentation material, and performing uniform stirring to form a smoking agent raw material; loading the smoking agent raw material into a mold by using a rubber hammer, and burying a section of commercially available mosquito-repellent incense into one corner of the mold asa smoking agent igniter; and demolding, and air-drying, wherein the smoking agent can be used at the end of April in Jilin region in spring when the lowest temperature in a greenhouse is 8 DEG C or above, and can be used at least once every week in cloudy days or cloudy days in the morning, so that the harm of whitefly can be effectively prevented and treated.

Description

technical field [0001] The invention relates to a plant insect repellent, insecticide and fumigant and a method for using the same, and relates to the field of pest control in greenhouses. Background technique [0002] Whitefly is one of the important pests of crops planted in greenhouses. It has a wide range of hosts and harms hundreds of common plants such as vegetables, flowers, fruit trees, medicinal materials, pastures, and tobacco. Due to its strong reproductive ability, adult wing surface covered with white wax powder, it is not easy to stick to the liquid medicine, and its migration ability is strong, and it can quickly "come back" after spraying pesticides. Headache problem. Fumigants have a good control effect on group whitefly control. Currently, the fumigant components used to control whitefly in the market are mainly chemical agents, such as fumigants based on chemical pesticides such as isoprocarb to repel whitefly. The insecticidal effect is very good, but a...

Problems solved by technology

In chemical production, it is necessary to use chemical methods to extract the chemical substances in Mirabilis Himalayan, which can be used as insecticidal pesticides after secondary processing, which inevitably brings certain chemical pollution; at the same time, the complex chemical components of Mirabilis Himalayan are extracted method, it is difficult to realize for the first-line farmers; while using the method of lighting fumigation of Mirabilis Himalayan plants, the chemical components in Mirabilis Himalayan plants have limited insecticidal effect on whitefly, and can only be treated by fumigation. It plays a short-term role in repelling whiteflies, and whiteflies will "come back" after the smoking is stopped. The effect of direct fumigation of Mirabilis Himalayan plants is limited
