Detailed Guide to the Application Technology of Longkejun in Rice Cultivation
Currently, it is the season of frequent typhoons and rainstorms, and also a period when rice diseases are prone to occur. The application technology of 20% Longkejun suspension concentrate on rice is as follows: To control bacterial foot rot of rice, use 100 grams of 20% Longkejun per mu diluted in 50 kg of water, spray the first application at the early stage of disease onset, then spray once every 7-10 days, for 2 consecutive applications, with remarkable control efficacy. For rice bacterial leaf blight, spray promptly when diseased plants are found in the field or after typhoons and rainstorms, using a 500-700 times dilution of 20% Longkejun for 2 sprays, at an interval of 7-10 days, with control efficacy reaching about 80%

Introduction to the Characteristics and Cultivation Key Points of the Rice Variety Lühwangzhan
Variety overview: Lühwangzhan was bred by the New Variety Breeding Laboratory of the Rice Research Institute, Guangdong Academy of Agricultural Sciences. Years of large-scale trial planting across the province have shown that it is an early-to-mid-maturing new rice variety with good yield potential, wide adaptability, excellent grain quality, and good overall combining ability. This variety is especially suitable for planting in the mountainous areas of northern Guangdong, and grows best in fields with medium or higher fertility. It is the improved variety with the shortest whole growth period among the varieties currently promoted in Guangdong Province. This variety has been included in the first batch of high-quality rice varieties under the Leapfrog Program jointly launched for the first time by the Ministry of Finance and the Ministry of Agriculture of China.

Green copper emulsion is highly effective against rice bacterial leaf streak
In an average epidemic year, the control efficacy reaches 85-91%, which is 10-15 percentage points higher than that of Japanese-made chlorothalonil. Method of use: in an average epidemic year, spraying twice is sufficient. The first spray is applied at stages 2-4 of young panicle differentiation in rice; 7 days after treatment the disease tends to stabilize, new acute lesions decrease significantly, and the original lesions stop developing after turning yellow. The second spray is applied 10 days later, using 100 mL of 12% green copper emulsion per mu each time, diluted 500-600 times for spraying. After 20 days, the rice leaf color turns noticeably greener, and the newly emerged flag leaf and the second leaf from the top have no
