Abstract

The invention relates to ampullaria gigas-killing granules containing metaldehyde and tea saponin. The effective ingredients consist of the metaldehyde and the tea saponin, and the weight ratio of the metaldehyde to the tea saponin is (2-5):(1-3). The ampullaria gigas-killing granules containing the metaldehyde and the tea saponin can effectively control harm of ampullaria gigas to rice; meanwhile the two effective ingredients are synergistic remarkably, the use amount of each piece of pesticide can be reduced effectively, the pesticide cost is reduced, and development of resistance of the harmful ampullaria gigas is delayed.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a snail-killing granule containing metaldehyde and tea saponin. Background technique [0002] Apple snails are one of the main pests in the growth process of rice in Guangxi. Every April-June and August-October is the period of egg laying and egg hatching, and it is also the peak period of concentrated damage to adult snails and old young snails. Apple snails harm rice, mainly by devouring rice leaves, resulting in fewer seedlings and missing plants at the seedling stage, requiring multiple seedling replacements; at the tillering stage, they bite off the main tiller and effective tiller of rice, resulting in a reduction in effective ears and a yield reduction of more than 20%. [0003] Metaldehyde, English name: metaldehyde, is a highly selective molluscicide, which has a certain attractant effect on apple snails. The plant does not absorb the drug, so it will not accumulate ...
