Effervescent tablets for preventing and treating rice grubs and preparation method thereof

Abstract

The invention discloses effervescent tablets for preventing and treating rice grubs and a preparation method thereof. The effervescent tablets are prepared from, by weight, 30-40 parts of pink plumepoppy herb, 20-32 parts of datura seeds, 18-30 parts of leaves of nerium odorum, 8-20 parts of radix sophorae subprostratae, 8-16 parts of acid source, 8-16 parts of alkali source, 2-4 parts of lubricating agent, 50-60 parts of filler, 4-8 parts of adhesive, 2-4 parts of disintegrating agent and 1-3 parts of wetting agent. According to the effervescent tablets for preventing and treating the rice grubs, pink plumepoppy herb, datura seeds and leaves of nerium odorum with neurotoxicity on the rice field grubs are added firstly, nervous excitation of the grubs is caused, acetyl choline reacting is interdicted, convulsion and spasm happen, a stomach poisoning effect is achieved on the grubs, and the intestinal tissue and other digestion and absorption organs are damaged; on this basis, radix sophorae subprostratae with a broad-spectrum antibacterial function is added, the two substances are compounded and added and achieve a synergistic effect, and the rice grubs can be effectively killed.

Description

technical field

[0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to an effervescent tablet for controlling rice pests and a preparation method thereof. Background technique

[0002] Pesticide effervescent tablet is a water-dispersible tablet that is directly put into paddy fields without pesticide dust or mist. Therefore, when the tablet meets water, it can quickly generate a large number of air bubbles to escape from the water, and the water looks like boiling, so it is called an effervescent tablet. Effervescent tablets were used in medicine earlier, but effervescent tablets used in agriculture have just started recently and have attracted people's attention. They can be widely used in places with water such as rice fields, ponds and lakes to prevent and control various diseases. Weeds, pests and plant diseases.
