New disease-resistant, high-yield rice variety launched by Bayer CropScience
On May 14, 2008, Bayer CropScience announced the launch in India of ArizeRDhani, the world's first hybrid rice variety resistant to bacterial leaf blight. Compared with conventional varieties, this new variety can increase yields by 20%-30% and provides the crop with strong protection against the highly destructive bacterial leaf blight. "Rice is a staple food in many developing countries and emerging markets. Although global demand for this crop continues to grow, the occurrence of diseases can greatly affect harvests and threaten food supply.

A Detailed Explanation of Eight Advanced Rice Transplanting Methods
1. Improved Intensive Cultivation: Transplant young seedlings early at the 3-leaf to 4-leaf 1-heart stage. Fields with good water sources should be transplanted early, while fields with poor water sources can be transplanted slightly later. Both dry-raised and water-raised seedlings are suitable, but basal fertilizer must be applied in full, the soil deeply plowed and leveled, strong seedlings selected as much as possible, and transplanting done in shallow water; both row spacing and hill spacing are 1 chi 3 cun, with three individual plants per hill spaced 3 cun apart in a triangular arrangement. This transplanting method has density within sparseness and sparseness within density, minimizing competition among plants for nutrients and sunlight to the greatest extent, which benefits individual plant development and thus can greatly increase yield. It is the most advocated transplanting method today. Two

Four key points for rice management in August: seize the critical period to ensure a bumper harvest
1. Apply rice field herbicides at the right time. To eliminate weeds in the rice field, herbicides should be applied at the right time. This saves labor (no need for intercultivation) and money (about 2 yuan per mu for chemicals), and also resolves the conflict of weeds competing with rice seedlings for fertilizer and light, which restricts the normal growth and development of rice seedlings. The specific method is: 5—7 days after transplanting, apply per mu 20 grams of Caocaolong or 60—100 grams of Dingbian mixed with urea (combined with topdressing), fine sand, or dry mud powder 30—40 jin, broadcast after the dew has dried, and maintain a shallow water layer for 4—
