Embodiment 1
[0037]Example 1: put tribenuron-methyl, bentazone, and clopyralid weighed according to the weight ratio into the mixer, add 5L of tap water, stir evenly, the stirring speed is 70r / min, and then add according to the weight ratio Sodium dodecylbenzenesulfonate, alkylphenol polyoxyethylene ether, polytrisiloxane, fully stirred and mixed, bottled and sealed. Among them, the weight percentage of each component is 20% of tribenuron-methyl, 30% of clopyralid, 40% of bentazone, 5% of sodium dodecylbenzenesulfonate; 4.8% of alkylphenol polyoxyethylene ether, polysilicon Oxane 0.2%. In 2010, a small-area control experiment was carried out on the natural grassland with serious hazards of Ligmus chinensis, located in Gongga Village, Taxiu Township, Guinan County, Hainan Prefecture, Qinghai Province. For conventional knapsack sprayer spraying, the dosage per hectare is 3000g, the spraying height is 1 meter, the spray width is 2 meters, and the pace is 1 meter / second. After 30 days of spr...
