Cotton knowledge: Attention must be paid to the prevention of diseases, pests and weeds during the cotton seedbed stage
Diseases, pests and weeds during the cotton seedbed cultivation period are the first disasters that cotton has encountered in its life. In this regard, some farmers cannot pay attention to it and think that prevention and control or not prevention and control are irrelevant. In fact, if some diseases, insect pests and weeds that occur more frequently in different seasons are not controlled in time, it will have a great impact on whether we can obtain enough high-quality seedlings for transplanting in the field in the future. Therefore, the control of cordyceps in cotton seedbed stage must be paid attention to. The specific control method is to first control underground pests such as cutworms and earthworms. When mixing the soil in the cotton seedbed before making pots, use 40 grams of 25% carbaryl wettable powder per 18-meter-long seedbed. First, mix the agent with water and pour it evenly. Bed soil, mix thoroughly and then make a bowl; to remove weeds in cotton seedbeds, you can use 5 ml of 36% clonadine emulsifiable concentrate or 20% dioxalate EC per 18-meter-long seedbed before covering the cotton seeds with soil and covering with film. Spray 6 to 7 ml of oxamamine EC to 2 kg of water on the bed surface. Spray evenly during application to prevent missed sprays and repeated sprays.
