Description

technical field

[0001] The invention relates to a preparation method, in particular to a preparation method for preventing and treating cotton anthracnose. It belongs to the technical field of planting pesticides. Background technique

[0002] Cotton, with milky white flowers, turns dark red shortly after flowering and then withers, leaving green cotton bolls with cottonseeds inside, and the fluff on the cottonseeds grows from the skin of the cottonseeds. When the bolls mature, they split open, exposing the soft fibers. The fibers are white or white with yellow, about 2-4 cm long, containing about 87-90% cellulose, 5-8% water, and 4-6% other substances. 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 c...

Examples

Embodiment 1

[0009] Example 1: 5000 grams of tea seed cake, 5000 grams of coptis, 5000 grams of tobacco, 5000 grams of pagoda tree leaves, 3000 grams of neem leaves, 2000 grams of spicy ginger, and 10000 grams of garlic.
