Problems solved by technology

In the 21st century, machine-transplanted rice seedlings, as the main rice mechanized cultivation measure, have been popularized and applied on a large scale. Due to the difficulty in implementing relevant measures and technologies in the process of seed soaking in large-scale industrial seedling cultivation, the bakanae pathogens are resistant to prochloraz. The occurrence of bakanae disease has exacerbated the spread of bakanae disease on rice

Abstract

The invention discloses a pesticide composition for preventing and treating rice seed-borne diseases, a preparation method and application of the pesticide composition. The pesticide composition is prepared from prothioconazole and cartap, and the mass ratio of effective components of the prothioconazole and the cartap is (1 to 400) : (1 to 500). The pesticide composition is mainly used for seed soaking of rice seeds to prevent and treat rice bakanae disease and aphelenchoides besseyi disease.

Description

technical field [0001] The invention relates to a new application of pesticides, in particular to a new application of pesticides with prothioconazole and cartap as main active ingredients. Background technique [0002] Rice bakanae disease is a systemic fungal disease that harms rice and is widely distributed in various rice regions in the world. In the early 1980s, with the advancement of rice indica to japonica in my country, the hazards of rice bakanae disease increased year by year, and attracted the attention of relevant departments. Carbendazim became the first choice for the control of rice bakanae disease at that time and was widely used, effectively controlling the spread of rice bakanae disease. Ten years later, in the 1990s, due to the popularization of dry bed seedling raising technology, the high temperature and high humidity environment of the seedbed promoted the reproduction and infection of the bakanae pathogen. At the same time, bakanae pathogens develop...
