Weeds "Contraceptives" Let Off the Weeds
Australian scientists are currently developing weed “contraceptives,†which can greatly reduce the use of toxic sprays. Once successfully developed, Australian farmers can reduce hundreds of millions of Australian dollars in investment each year. Scientists are developing weeds "contraceptives" According to Australian Broadcasting Corporation reported on the 18th, Australian scientists are currently developing weeds "contraceptives", which can greatly reduce the use of toxic sprays. Once successfully developed, Australian farmers can reduce hundreds of millions of Australian dollars in investment each year. According to the research plan, scientists hope that by "spoiling" the weeds, they believe that they are breeding themselves and thus "turn off" their reproductive systems. Scientists hope to mimic the chemicals used in the laboratory to allow plants to repel their pollen and thereby prevent breeding. Once injected onto a certain kind of weeds, this chemical can act as a "contraceptive", causing it to mistakenly believe that they are self-fertilized. Newbiggin, an associate professor of the Botany College of the University of Melbourne and one of the principals of the study, explained that many plants have male and female reproductive organs and are able to reproduce themselves. This is called "self-affinity." But he also said: "A large number of weeds bloom with both male and female characteristics. They should be able to reproduce themselves, but we must prevent them from reproducing themselves." Nature gives these weeds a way to probe themselves. Pollen protein. Once activated, it can initiate chemical mechanisms that prevent the pollen "sperm" from entering the eggs in the plant's female organs (style). Professor Newbykin called this function a chemical "condom," which would give plants what botanists call "self-incompatibility." The first offensive goal is to teach wild radishes New Guinean that if the plan succeeds in developing weed “contraceptivesâ€, this will save Australia’s agriculture a lot of money every year, significantly reducing the amount of toxic sprays that are sprayed into the fields. The plan was launched by the Australian Weed Management Cooperative Research Center on the 17th. Dr. Andrew Yang and Dr. Steve Swin, Scientists of the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO), also participated in the program. The scientist's first goal was the wild radish, which caused the farmer hundreds of millions of Australian dollars every year. If the research is successful, scientists will eventually use the same technology to deal with another important agricultural weed, perennial ryegrass. Plans to make significant progress within three years Sprays with "contraceptive" functions are non-toxic and do not involve genetic variations. Since most do not have the ability to identify their own pollen, they will not pose any threat to the crop. If scientists can prevent weeds from dropping new grass seeds into the soil, they will eventually “get off the hook,†and if farmers rely entirely on pesticides and herbicides, this is almost impossible to achieve. Professor Newbykin said: "We think the plan will make significant progress in three years."
