Monsanto will launch drought-tolerant transgenic cotton varieties
Monsanto, the world's leading-edge seed company, is developing a drought-tolerant genetically modified cotton variety that could be launched in 2015 and used for commercial cultivation.
"We hope to launch a drought-tolerant cotton seed by the middle of the next decade," said JerrySteiner, vice president of Monsanto. But five years later, we can announce whether we can launch drought-tolerant seeds at that time. "
Monsanto officials also said the company is currently working on genetically modified seeds that can minimize fertilizer use.
The basic characteristics of genetically modified seeds are known to reduce the risk of insect pests, help farmers reduce input costs and reduce the use of pesticides.
Steiner said Monsanto did not charge Indian companies too much for technology, and the rumors were wrong.
Monsanto officials also said the company stopped launching a second genetically modified cotton seed Bollgard to China because of China's poor intellectual property record.
Steiner said Monsanto has been in India for 50 years and will continue to stay in India.
Monsanto officials said that the company's GM seeds are mainly concentrated in three crops, corn, soybeans and cotton, while the company is also actively developing high-yielding non-GM vegetable seeds.
He said that India's cotton water consumption is 35% higher, but its per unit yield is 20% lower than that of Egypt and the United States.
He said that the world's biological crops cover an area of 1.4 billion acres, and 10.3 million farmers grow biological crops, while 90 percent of the growers are in developing countries. From 1996 to 2006, farmers' income increased by more than 27 billion US dollars.

Control cotton diseases, insect pests and weeds at sowing date and seedling stage
This year, due to the influence of abnormal climate, the sowing time of cotton in our province was postponed. Under the condition of continuous low temperature, the growth and development of cotton was delayed, and the harm degree of diseases and insect pests was relatively aggravated. To this end, cotton is facing a more severe situation of pest control this year. From the beginning of sowing, we should firmly implement the key of each prevention and control technology, especially the technical link of drug selection. Now the main disease and pest control techniques at sowing time and seedling stage are introduced to the broad masses of farmers as follows: first, it is necessary to strictly control the chemical treatment of seeds at sowing time before sowing cotton.

Scientific Irrigation Technology of Cotton
Cotton is a straight root crop, the main root is deeply embedded in the soil, and it is a drought-tolerant crop. The period from budding to boll opening is the key period of water demand. 1. Conventional irrigation: the whole growth period is irrigated 3-4 times, the first irrigation is in the budding stage, that is, in mid-late June, the second irrigation is in the full bloom stage, that is, the middle of July, the third irrigation is in the flower and boll stage, that is, from the end of July to the beginning of August, if the weather is dry or sand leakage can be done again. If there is a lot of rainfall, if there is no drought, it can no longer be watered. The irrigation quota, in addition to 120 square meters of water per mu, will be irrigated every time during the growth period.
