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.

Moderate to slightly light occurrence of the second generation of rice stem borers in Suijiang County in 2007
Rice stem borers in our county include the yellow stem borer (Scirpophaga incertulas), the striped stem borer (Chilo suppressalis), and the giant stem borer (Sesamia inferens). In the riverside area, 3 generations occur per year; in the mid-mountain area, 2 generations occur per year. At present, the first generation in the riverside area has ended, and the second generation is beginning to occur successively. According to observations at our station's Fengchi pest and disease monitoring point, this year's second-generation moth flight began on June 10, 1 day earlier than last year and 2 days later than normal years, with the peak day on June 18, 1 day later than last year and 8 days earlier than the historical average; by June 25, a cumulative total of 234 moths had been trapped, with the yellow stem borer, striped stem borer, and giant stem borer accounting for 94.9

How was the trial on early breeding of rice field eel fry in greenhouses carried out?
At present, cage culture of rice field eels is concentrated on collecting fry in July, which gives a high survival rate and low farming risk. But concentrating purchases means few fry sources, high prices, and a low weight-gain multiple. If fry are purchased earlier, the unstable temperature leads to a high mortality rate of the fry. How can this problem be solved? We carried out a trial on early breeding of rice field eel fry in greenhouses, and a brief summary of the trial is as follows: 1. Trial conditions 1. Trial pond: a newly excavated artificial water surface, 250 m long, 4 m wide and 1.5 m deep, with an area of 1000 sq m. The water source is lake

What is low-sugar rice? Introducing this miraculous rice variety
Low-sugar rice is a low-sugar-type rice variety bred by Japanese scientists through years of effort. It is also the only new type of rice variety in the world with an outstanding blood-sugar-lowering effect. It has thus opened a new path for lowering blood sugar through dietary therapy. It has attracted widespread attention from scientists and diabetes patients around the world. Low-sugar rice combines both food and medicinal uses, and its most prominent characteristic is that its protein is rich in "GLP-1," which can greatly increase insulin secretion in the human body. This achieves the goal of inhibiting blood sugar elevation. It changes the current situation in which diabetes treatment relies solely on drugs
