Imidazolinone herbicides Survey Creation

On the advantages, but head 0I (1971) position Ij IJ Jingwei Gao replaced the former mostly glyphosate. Herbicides such companies by the United States cyanamid found. The created latitude and longitude from the random screening, that history is as follows:: V0HClH Ⅳ Ⅲ 0H \ r /, canthal Ⅵ compounds I initially as anti-spasm medication synthetic, cyanamid company in 1971 was carried out herbicidal activity assay, found a more good herbicidal activity, and further research. I as a lead compound to compound, in a series of pilot started, the discovered compounds AC94377 good activity as plant growth regulator; and then by the same study found that compounds Ⅱ has the role to promote plant growth; further study found that the herbicidal compound Ⅲ active than compounds I. Perhaps someone should ask, why not directly from a compound synthesized compounds Ⅲ but I walked around until after the synthetic compound by compound Ⅱ Ⅲ? As everyone knows, every invention is not as we imagine to happen. Is usually one step forward in the exploration,[link widoczny dla zalogowanych], and in most cases and sometimes in the detours, and then have a new discovery. There are commonly referred to as know-how. Actually is very simple. However,[link widoczny dla zalogowanych], the discovery of the secret of the technology is to pay a considerable price. This is also the launch of the magazine section of pesticides purpose,[link widoczny dla zalogowanych], hope you can understand some of the varieties of pesticides create latitude and longitude to display your rich imagination, coupled with your hard work and efforts, based on research results of others may be less motivated detours and efficient to create a more valuable new products. HH0HVRH2: Ⅶ cyanamid Xinjiang in the company's research staff has conducted on the basis of compounds Ⅲ-depth study found that the lead compounds imidazolinone Ⅳ. Ⅳ compounds have good herbicidal activity though, but no selectivity. Researchers after the pyridine ring was benzene compounds into a V, be greatly improved herbicidal activity, the compound is the first commercialized imidazolinone compounds, later researchers Ⅳ and V of the compounds were optimized and development of pilot the number of species such as the compounds Ⅵ (i-mazapic), Ⅶ (imazethapyr,[link widoczny dla zalogowanych], R: CH3; imazamox, R = CHO) and so on.
