Description

technical field [0001] The invention relates to a plant medicine, in particular to a plant medicine for controlling cotton toothworm. It belongs to the technical field of planting pesticides. Background technique [0002] Cotton is one of the most important crops in the world, with high output and low production cost, which makes the price of cotton products relatively low. Cotton fiber can be made into fabrics of various specifications, from light and transparent voile to thick canvas and thick velveteen, suitable for making all kinds of clothes, furniture cloth and industrial cloth. Cotton fabrics are strong and durable and can be washed and ironed at high temperatures. Cotton is comfortable to wear because it absorbs and releases moisture quickly. If it is required to keep warm, the surface of the fabric can be raised by brushing. Through other finishing processes, it can also make the cotton fabric anti-fouling, waterproof, and mildew-proof; improve the anti-wrinkle ...

Problems solved by technology

It overcomes the use of high-concentration pesticide spraying. Although the control effect is very good, the residual pesticide components in cotton are too high, which will cause harm to the human body, make the human body susceptible to various diseases, and easily cause the immunity of various functions of the human body to decline.
