Rice is an important field crop in China. In the process of rice planting, valerian is a common grass damage . Valerian is also known as grass head. It is a 1-2 herb of the genus Leguminosae. In recent years, the planting area of ​​alfalfa in Yangzhong City has been expanding, and the problem of grass damage in the field has been prominent. The main weeds are Mai Niang, Fan, Rice, and Pork. Today we will take a look at how we should eradicate rice weeds.
First, killing
Valerian can be planted after rice harvesting, or it can be cultivated in greenhouses. The herbicide herbicide glyphosate or paraquat should be used before sowing.
Second, the soil closure treatment of alfalfa can be shallow rotation or shallow sowing with river mud.
(1) Shallow rotation. After sowing, 50% dichlorpyrifos wettable powder 150-200 g plus 40-50 kg spray per acre can effectively block annual grass weeds, and the control effect on broadleaf grass is slightly worse. About 50 days.
(2) River mud sowing. Each acre is sprayed with 200% of a 50% dichlorfena wettable powder and water, and then sown by mud pouring. Here, the pesticide network suggests that dichlorfen is a pre-emergence soil blocking treatment agent, and the weeds that have been unearthed are poorly treated, and the weeds in the field should be removed before use. The amount of 50% diquat herbaceous wettable powder should not exceed 250 grams. Pay attention to the application of pesticides to ensure the effectiveness.
Third, stem and leaf treatment
In the early spring, stem and leaf treatment was carried out according to the occurrence of weeds in the field. For grass weeds, use high-efficiency grass cover per acre with 10.8% high-efficiency flupirtine emulsifiable concentrate 30-40 ml with water spray; for broad-leaved weeds such as swine fever and sorghum, use high gram per acre 50% Herbicidal suspension 45-60 ml spray or other alternative biological pesticides . Pay attention to picking after the safety interval.
