Detailed Explanation of the Seedling Raising Methods and Techniques for Large-Leaf Privet (Ligustrum lucidum)
The seedling raising method for large-leaf privet (Ligustrum lucidum) is as follows: before sowing in early spring, first stratify the seeds in moist sand for about 60 days. Sow in drills with a row spacing of 15 to 20 cm, at a seeding rate of 7.5 to 10 kg per 667 sq m, cover with soil 1 to 1.5 cm thick, and mulch with straw. Germination and emergence generally begin in mid-April; once some of the seedlings have emerged completely, remove the straw and thin the seedlings in time. One-year-old seedlings reach 40 to 60 cm in height and can be lifted for use as hedges; for street trees or courtyard landscaping, they need to be transplanted and grown on as large seedlings for 2 to 3 years, and when the seedlings reach 1.5 to 2 m in height they can be transplanted; large seedlings must be lifted with a soil ball, and part of the branches and leaves should be pruned off.

Causes of Leaf Drop in Golden Privet During the Growing Season and Solutions
Golden privet (Ligustrum × vicaryi) is an excellent colorful shrub. In practical cultivation in some places, during the growing season its leaves, especially new leaves, successively develop spots, which then progress to drying up, leaf drop, and the branches gradually die back from top to bottom, with a small portion dying. According to surveys, the deaths mostly occur in the middle of the planting plots, while the plants around the edges grow well. The causes are mainly the following two aspects. 1. Caused by disease.

How to control the tea green leafhopper? Efficacy trial of 10% imidaclothiz wettable powder
Abstract of the efficacy trial of 10% imidaclothiz wettable powder against the tea green leafhopper: Field trials showed that 10% imidaclothiz wettable powder has good control efficacy against the tea green leafhopper, and the control efficacy of the 3000-4000x dilution still reached above 80% at 14 d after treatment. Keywords: imidaclothiz; tea green leafhopper; control efficacy. 10% imidaclothiz wettable powder is a nitromethylene systemic insecticide.

What are the control methods for leaf diseases of hot peppers?
The main leaf diseases of hot peppers include anthracnose, brown spot, bacterial leaf spot, and gray leaf spot. These diseases can occur alone or together, among which bacterial leaf spot is more severe, often causing early leaf drop or even complete defoliation, greatly affecting the yield and quality of hot peppers. It is currently the rainy season, and the high-temperature, high-humidity climate conditions favor the occurrence of leaf diseases in hot peppers. Control measures: 1. Agricultural measures: After rain or irrigation, carry out timely intertillage to reduce soil moisture. 2. Use 77% Kocide at 500 times dilution (used alone
