Control methods for the Ningxia ground pearl (Porphyrophora ningxiana) pest on licorice
It is distributed in all licorice-producing areas nationwide, generally causing damage from the seedling stage to the mature plant stage. The Ningxia ground pearl has 8 host plant species, all of which are perennial leguminous herbaceous perennials, with licorice suffering the most severe damage, while other hosts are only slightly affected. (1) Damage period and damage symptoms: Overwintering nymphs can move intermittently when the surface soil temperature reaches 6°C, and become frequently active when the daily average temperature exceeds 12°C, in order to search for hosts. Early March is the initial activity stage, mid-to-late April is the peak period for searching hosts, and by mid-May they have basically all settled. From late May to late July

Introduction to the Characteristics and Traits of the I You 86 Rice Variety
[Basic Information] I You 86 was developed by this institute through test crossing and selection in 1995 between the self-bred new restorer line R8608 (a composite cross progeny of Gui 630/Fei-//Conggui 314/IR8608) and You IA, which was selected and bred by the Hunan Hybrid Rice Research Center. After 4 consecutive years of trials and test plantings from 1996 to 1999, this combination showed high and stable yield, relatively good grain quality, and multiple resistance, with comprehensive traits significantly superior to the control Shanyou 64, and high seed production yield. This institute used Zhenshan 97A,

Rice midge harms rice, how can it be controlled effectively?
Rice midge, commonly known as red worm or red thread worm, damages the young roots and young shoots of rice with its larvae, causing floating seedlings, and feeds on the embryo and endosperm of ungerminated seeds, preventing the seeds from germinating. Rice seedling fields and direct-seeded fields suffer severe damage. The adult is a small moth, with wings shorter than the body; when resting, the front legs are raised and swing up and down. The larvae are red or pale yellow, with a limb-like protrusion on the ventral side of the prothorax. It occurs 2-3 generations per year, and the first generation damages rice. It overwinters as nymphs and adults in weeds. Adults appear in early May of the second year, and lay eggs in late May.

Timely Control of the Rice Leaf Roller Is Essential and Cannot Be Delayed
The rice leaf roller is one of the major rice pests in our province. Its larvae damage the leaves, turning rice leaves into a mass of withered white. Especially when it attacks at the booting or heading stage, it will cause a sharp decline in rice yield. This pest has seven generations a year, and the second-generation larvae are the most numerous and cause the most serious damage to early rice. If control is not timely, it will break out in a major outbreak during the heading period, causing incalculable losses. For forecasting the rice leaf roller, the appropriate control timing should be determined based on the forecast of the occurrence period. Based on past conditions, investigation should begin 4 days after the peak of the moth flight

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
