What is Roundup Ready and what are the Roundup Ready varieties? Roundup Ready refers to a trademarked line of genetically modified crop seeds that are resistant to Roundup. These crops are called Roundup Ready.
Who came up with Roundup?
John Franz, Monsanto’s chemist, first identified Glyphosate as an herbicide in Roundup in the year 1970. In ラウンドアップ , the vast majority of herbicides in the ag field were pre-emergent. That is, they were sprayed before plants and weeds had appeared. The post-emergent action of glyphosate to control a large number of grass and broadleaf weeds is quite different. This, is when combined with its remarkable environmental properties (soil inactivation, rapid degradation, no carryover) and toxicological characteristics (extremely minimal toxicity for beneficial and mammals), made it an outstanding product.
What year was it when Roundup introduced?
Roundup(r) that was initially introduced on the market as a broad spectrum herbicide in 1974, rapidly became one of the most well-known agricultural chemicals worldwide. ラウンドアップ (r) was initially applied on railway tracks, in ditches and on the fields between growing seasons. It allowed ranchers and farmers to control broadleaf and grass plants that had sprouted out of the soil.
The Roundup Ready GMOs followed.
Monsanto scientists became impressed by the breakthrough advancements in Recombinant technology in the 1970s. Monsanto scientists realized the many benefits Roundup(r could bring to farmers. It can be applied directly on crops to eliminate weeds. A small team of scientists (Rob Horsch, Steve Rogers and myself) led by Dr Ernie Jaworski, began working on this issue. In https://search.rakuten.co.jp/search/mall/%E3%83%A9%E3%82%A6%E3%83%B3%E3%83%89%E3%82%A2%E3%83%83%E3%83%97+%E3%83%9E%E3%83%83%E3%82%AF%E3%82%B9%E3%83%AD%E3%83%BC%E3%83%89/ had developed the very first methods to insert genes in plants. Our attention shifted to the creation of virus-resistant plants, which are resistant to insects and also Roundup.
It was known that glyphosate could inhibit the biochemical process in plants that made aromatic amino acids (animals and humans don’t have this pathway which is why Roundup has a high degree of mammal safety) and that glyphosate was broken down very rapidly in the soil by microorganisms. In the mid-1980s our scientists had discovered plants and microbial genes which conferred higher tolerance to herbicides through laboratory testing. In 1987, the USDA authorized the first field test of Roundup Ready plants. https://mujin-heri.jp/yakuzai/js-55.html was a Roundup resistant crop of genetically modified tomatoes that proved tolerant to Roundup. In the following years the bacteria that would become the gene that would become the Roundup Ready trait was isolated and then introduced into the crops.
Let’s consider soybeans as an example. First, we need to address two issues. What are Roundup Ready soybeans? And how are they made? Roundup Ready Soybeans are a genetically engineered type of soybeans with its DNA altered so that they are resistant to the herbicide Roundup. These soybeans can withstand Roundup because every soybean seed has been injected with the Roundup Ready gene prior to planting. This allows farmers to spray their fields with Roundup Ready herbicides in order to destroy weeds but not the crops.
Roundup Ready crops, which were introduced in 1996 revolutionized agricultural research and agriculture. Roundup resistance was immediately acknowledged by farmers and widespread adoption began. Today, over 90% of U.S. soybeans and cotton utilize Roundup Ready crops. Apart from reducing and improving weed management systems which improved yields of crops Roundup Ready crops cut down on tillage and reduced equipment costs and also allowed for more efficient harvests due to “cleaner fields” with fewer weeds. The increased use of conservation-tillage has had a major impact on the environment. Farmers can lower their carbon footprint and energy use by decreasing plowing. But this also keeps soil structure intact and helps reduce erosion. This was equivalent to removing 28.4 million tonnes of carbon dioxide in the atmosphere. This also means that 12.4 millions of cars were eliminated from the roads each year. ( ラウンドアップ : and PG Economics).
