How to scientifically control the first generation of the second-brood striped stem borer in single-season rice
Control recommendations 1. For early-sown and early-transplanted single-season rice fields, carry out a full control treatment once from June 20-25, targeting mainly stem borers and small brown planthoppers, and also controlling early-occurring leaf folders and rice thrips. Use 5% fipronil (Regent) suspension concentrate at 40-50 ml/mu, diluted in 30 kg of water for spraying. 2. For fields where rice stripe disease has occurred, on the basis of pulling out and removing diseased plants, promptly apply chemicals to control small brown planthoppers. Use 40% chlorpyrifos (Xinnongbao, Saiben) at 100 ml/mu, diluted in 30 kg of water for spraying, and repeat the treatment after an interval of 5-7 days.

What herbicide is used to control rice barnyardgrass? Rongjie is a highly effective herbicide.
Rongjie is a rice field herbicide newly developed by Dow AgroSciences of the United States, with penoxsulam (25 g/L oil suspension concentrate) as its main ingredient. Years of trials and demonstrations have proven that Rongjie is particularly outstanding in controlling rice barnyardgrass, a vicious weed in paddy fields in Northeast China. In the rice fields of the Fushun area, there are two types of barnyardgrass: water barnyardgrass and rice barnyardgrass. Water barnyardgrass has no auricle or ligule, while rice barnyardgrass, though also lacking an auricle and ligule, has fine hairs on the internodes between the leaf and leaf sheath. In recent years, after conventional barnyardgrass-killing herbicides were applied in rice fields, water barnyardgrass has been effectively controlled,

Analysis of the Benefits of Rice-Water Bamboo Crop Rotation and Water Bamboo Cultivation Techniques
Chongxian Town, Yuhang District, Hangzhou City, is located in a plain water-network area and was originally mainly engaged in rice cultivation, along with some aquatic crops such as water bamboo, arrowhead, and lotus root. During agricultural development and industrial restructuring, Chongxian Town utilized local water and soil resources to vigorously expand the rice-water bamboo rotation area, and treated water bamboo production as a high-efficiency agricultural undertaking within the vegetable basket project. The district, town, and village invested 2 million yuan to establish the Chongxian Village water bamboo demonstration park. In 2005, the Hangzhou Municipal Agricultural Comprehensive Development Office designated it as a national agricultural comprehensive development high-tech demonstration
