What causes premature senescence in cotton seed production fields? How should it be prevented and controlled?
As cotton seed production fields are planted year after year, premature senescence occurs from time to time, and has become an important factor restricting the increase of per-unit yield and the improvement of quality in seed production fields. 1. Causes of premature senescence 1. Continuous successive cropping of seed cotton fields In cotton-growing areas, cotton has been planted continuously on the same land for many years, resulting in a lack of organic matter in the plow layer, which cannot satisfy the soil's sustained fertilizer supply effect. At the same time, successive cropping causes the accumulation of pathogenic bacteria in the soil and a reduction in the number of insect-resistant bacteria, blocking the normal growth of the cotton root system, thereby affecting the upper growth of cotton and causing premature senescence. 2. Cotton

How are cotton seedling diseases diagnosed and controlled?
Diagnosis and Control of Cotton Seedling Diseases Cotton seedling diseases are numerous, but they can be grouped into two main types: root diseases and leaf diseases. Root diseases often cause seed rot and sprout rot before emergence, and root rot and stem-base rot after emergence, and are the main cause of missing plants and broken rows in cotton fields. Common ones include damping-off (Rhizoctonia), anthracnose, red rot, and Pythium damping-off. Leaf diseases damage the cotyledons, true leaves, and stems of cotton seedlings, and in severe cases the stem tips and leaves wither and drop off. Common ones include black spot, brown spot, cotton seedling blight, and stem blight. This film focuses on summarizing and introducing several

How can bamboo-leaf grass in cotton fields be controlled effectively?
First choose a suitable herbicide, then decide the dosage according to the weed species, leaf age and humidity level. For example, when using fluazifop-P-butyl to control annual weeds, when soil moisture is suitable, the effective ingredient dosage per mu is 9-17 grams; under drought conditions it is 17-24 grams; to control perennial weeds, the effective ingredient dosage per mu is 27-45 grams. Spray on the stems and leaves when grass weeds are at the 2-5 leaf stage. In summer, apply the herbicide on windless days, in the early morning and evening when temperatures are lower; uniform spraying is required, and keeping

How should the four common bean diseases be prevented and controlled?
1. Root drowning: Beans prefer moisture and tolerate drought but not waterlogging. Therefore, on the basis of ridge cultivation, small amounts of water should be applied to avoid water accumulation in the field, which prevents the roots from breathing and causes plant death. Control measures: Avoid flood irrigation. If there is heavy rain, drain the water promptly. After the weather clears, if conditions permit, appropriate shallow hoeing can be done to increase soil permeability and improve root vitality. 2. Phytophthora blight: It mainly damages the stems and vines, and sometimes the leaves and pods are also affected. It constricts at the base of the stem, causing the upper part to wilt and die. When humidity is high, white mycelium is produced on the diseased part.
