Seed soaking agent for preventing bacterial wilt of ginger, preparation and uses thereof

Abstract

The invention provides a seed soaking agent for preventing ginger bacterial wilt, as well as a preparation method and an application thereof, which belongs to the technical field of pesticide. The seed soaking agent consists of 30 to 60 percent of 80 percent sodium sorbate, 35 to 65 percent of 40 percent chlorothalonil, 0.5 to 1 percent of 80 percent sodium natrophenolate, and 1 to 5 percent of 95 percent sodium sulfite. The sodium sorbate and the chlorothalonil are mixed, ground and then passed through a 200-mesh sieve; the sodium natrophenolate and the sodium sulfite are mixed, ground and then passed through an 80-mesh sieve; and mixtures are mixed by a mixer again and then are quantificationally packaged so as to obtain the seed soaking agent. Every 100 grams of the seed soaking agent are prepared into 250 times of solution (namely 25 kilograms of solution) in order to soak 250 kilograms of ginger seeds for 20 to 30 minutes. The field control effect of the agent can reach 80 to 85 percent, and is improved by 24 to 32 percent in contrast with comparison control effect between 48 and 61 percent. The agent has the advantages of low cost which is 5 yuan per mu, sufficient raw materials, food grade, low toxicity, safety, harmlessness, simple production process, no wastewater and no waste residue.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a seed soaking agent for preventing ginger blast and its preparation method and application. Background technique [0002] China is a big exporter of ginger. The national ginger planting area is 1.5 million mu. Yunnan is a major exporter of ginger. Ginger is one of Yunnan's important export commodities, especially Luoping small yellow ginger. The products have been exported to 32 countries in Southeast Asia, the United Arab Emirates, Europe and the United States. Countries and regions, the market prospects are good. But ginger blast is the main and serious disease in ginger production, all there is to take place in each ginger area of ​​China, and ginger blast causes ginger production loss to account for 15-50% of ginger total output (Li Xiangdong etc., Luoping ginger disease wormwood The research and application demonstration of the whole-process damage control technology, "...
