Integrated Control Methods for Soybean "Fire Dragon Seedling"
In Wudalianchi City, Heilongjiang Province, the soybean area is 950,000 mu, with a continuous cropping area of 930,000 mu, accounting for 97.8% of the soybean sown area. Through investigation, the area affected by soybean "Fire Dragon Seedling" is around 96.5%, with most yield reductions between 20 and 50%, and some plots reaching total crop failure. It can be said that due to the influence of the market economy, the continuous cropping area of soybean cannot be controlled, but through integrated control, the occurrence of soybean "Fire Dragon Seedling" can be reduced, enabling soybean to achieve high and stable yields. The integrated control techniques for soybean "Fire Dragon Seedling" are as follows:

Key Integrated Cultivation Techniques for the Prevention and Control of Premature Senescence in Cotton
Cotton premature senescence refers to the phenomenon in which cotton leaves wither, turn yellow and drop prematurely under suitable climatic conditions. In the field, it appears as interveinal chlorosis and yellowing of the leaves after the full flowering stage. The yellowing leaves begin at the point farthest from the main stem and develop from top to bottom and from the outside inward, with the leaves gradually drying up and dropping. Premature senescence has a considerable impact on cotton yield and quality; the earlier it occurs, the greater the impact, and it can generally reduce yield by 10%-40%. Cotton premature senescence occurs because the fertilizer and water requirements for normal growth during the vigorous growth period cannot be met, leading to premature aging and early leaf drop.

Cotton shows disease symptoms, integrated control with multiple measures
Symptom identification of cotton Fusarium wilt and Verticillium wilt. Cotton Fusarium wilt can occur throughout the entire growth and development period of cotton, but it occurs more severely at the seedling stage. If favorable conditions occur, it can also break out heavily at the adult plant stage. Sudden wilt type: leaves suddenly lose water, droop and wilt, leaf color is dark green, leaves become soft and thin, the whole plant dries green and dies, but leaves generally do not fall off, and petioles bend. Yellowing type: can occur at both the seedling stage and the adult plant stage.

Occurrence and Damage Characteristics of Tea Tussock Moth and Integrated Control Methods
In recent years, with the development of pollution-free tea and organic tea production, the frequency and amount of chemical pesticides used in tea gardens have decreased, and some tea gardens even do not use chemical pesticides, resulting in aggravated damage by the tea tussock moth in a short period. In the county where the author works, tea tussock moth damage has occurred for several consecutive years, and after being damaged, the tea plants were left with only bare branches, greatly affecting the economic income of tea farmers. 1. Damage symptoms: The tea tussock moth larvae bite and feed on leaves, causing leaf notches and bare branches. 1st-2nd instar larvae gather on the underside of leaves to feed on the mesophyll, leaving only the epidermis and veins, and the damaged leaves appear transparent
