[0031] 3. Preparation of Konjac extract

[0032] The extract of C. betel is prepared according to the following steps: wash the rhizome of C. betel, dry in the shade, pulverize with a pulverizer, and pass through a 50-mesh sieve to obtain a pulverized product; add 10 times the amount of 95% ethanol to the obtained pulverized product, soak at room temperature for 48 hours, Extract with ultrasound for 60 minutes, then filter with a Buchner funnel, and collect the filtrate; repeat the extraction 2-3 times; combine all the filtrates; concentrate the obtained filtrate under reduced pressure to a paste with a relative density of 1.20, and freeze-dry it into a powder. Obtained betel extract.

[0033] All embodiments of the present invention all adopt the above-mentioned method to prepare the Pseudocarpus extract of gained.

Abstract

The invention relates to a mulberry insecticidal composition having safety to bombyx mori, which is formed by effective components and an excipient, the effective component is composed of a piper sarmentosum extract product and a component A, and the component A is at least one of pyriproxyfen or pymetrozine. The added piper sarmentosum extract product is taken as one of the effective components, the piper sarmentosum extract product has low prevention and control effect for mulberry gall-midge, and can be mainly used as a synergist, after the piper sarmentosum extract product is added, the prevention and control effect of pyriproxyfen or pymetrozine can be obviously increased, the application amount and concentration of a chemical agent are reduced, so that the residue of the chemical agent on the mulberry leaves is reduced, and the mulberry insecticidal composition has higher security for bombyx mori.

Description

technical field [0001] The invention relates to the field of agricultural insecticides, in particular to a mulberry insecticidal composition for controlling mulberry gall midges. Background technique [0002] The mulberry gall midge Contarinia sp., also known as the mulberry midge, belongs to the Diptera gall midge family and is an important pest that harms mulberry trees. The harm of the mulberry gall midge is mainly that the larvae parasitize the inner side of the young leaves of the terminal buds of mulberry trees, and suck the juice of the young shoots after stabbing the terminal bud tissue with the mouthparts, causing the terminal buds to change color, bend, wither, blacken, fall off, and "blind". top". The damage of mulberry gall midges is also manifested as a layered phenomenon, that is, the terminal buds are "blind top". After a period of time after the branches are capped, the upper axillary buds germinate and are parasitized by the next generation of larvae. If t...
