The bollworm evolved so quickly that it could even swim in pesticides

In the early 1990s, a large area of ​​cotton bollworm disaster occurred in China, and the cotton yield in some cotton regions decreased by 80%. Recalling the cotton bollworm pests of the year, many cotton farmers are still changing their colors. Wang Aiguo, a cotton farmer in Xihua County, Henan Province, said: “In the beginning, a few milliliters of pesticides will kill bollworms, but this bug soon became resistant to insects. Later, a bucket of water added more than 20 milliliters of pesticides, and still kill. Some people put cotton bollworms in the pesticide solution, and they actually swim around.†As our country’s cotton industry has been shaken up by cotton bollworms, foreign multinationals have mastered the “treasure†of pest management—genetically modified technology. And produce transgenic insect-resistant cotton. A so-called transgenic plant is a process in which a piece of genetic material (DNA) from a plant or a microorganism or even an animal is transferred to another different plant so that a desired biological trait or product can be expressed in the latter cell. . The transgenic insect-resistant cotton, by transferring a DNA fragment of bacteria into the cotton, let the cotton bollworm die as soon as it is eaten. Thanks to the efforts of our scientists in recent 10 years, the research on transgenic insect-resistant cotton in China has made breakthrough progress, becoming the second country in the world with independent intellectual property rights for Bt insecticidal genes and autonomous breeding of new varieties of transgenic insect-resistant cotton. It is understood that in addition to the performance of domestically produced transgenic insect-resistant cotton, and the foreign insect-resistant cotton is also generally more than its production increase of more than 10%, hybrid insect-resistant cotton production is increased by more than 20%. By 2005, the domestically-established transgenic insect-resistant cotton has been promoted to more than 90 million mu, creating more than 150 billion yuan in social and economic benefits.
Salted Kelp Roots
The original ecological kelp means that we pack the young kelp with saturated salt water directly after washing without any preservatives.Original ecological products are the favourite of housewives.
