Cyproconazole
Cyproconazole is an agricultural fungicide of the class of azoles, used on cereal crops, coffee, sugar beet, fruit trees and grapes, and peanuts, on sod farms and golf course turf and on wood as a preservative. It has been used against powdery mildew, rust on cereals and apple scab, and applied by air or on the ground or by chemigation. In the US approval began in 1993, and it was introduced to the market by then Sandoz in 1994, which as of 2000 has been Syngenta. EU approval began in June 2011 and expired after 10 years in May 2021. It is persistent in both soil and water systems. The European Community has classified cyproconazole into carcinogen category 3 as limited evidence, as reproductive toxicant, and as dangerous for the environment, because very toxic to aquatic organisms, causing acute and long-term adverse effects in the aquatic environment. While it is moderately toxic to mammals and most aquatic organisms, earthworms and honeybees, it is highly toxic to bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemigation
Fertigation is the injection of fertilizers, used for soil amendments, water amendments and other water-soluble products into an irrigation Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has bee ... system. Chemigation, the injection of chemicals into an irrigation system, is related to fertigation. The two terms are sometimes used interchangeably however chemigation is generally a more controlled and regulated process due to the nature of the chemicals used. Chemigation often involves insecticides, herbicides, and fungicides, some of which pose health threat to humans, animals, and the environment. Uses Fertigation is practiced extensively in commercial agriculture and horticulture. Fertigation is also increasingly being used for landscaping as dispenser units become more reliable and ea ...

Golf Course Turf
Golf course turf is the grass covering golf courses, which is used as a playing surface in the sport of golf. The grass is usually maintained by a greenskeeper to control weeds, insects with pesticides, plant fungal diseases with fungicides and to introduce nutrients such as nitrogen fertilization. The grass is kept at a constant height by mowing. Nutrient management Nitrogen is the nutrient required in greatest amount by turfgrass. During an autumn season, rates of nitrogen (N) application should be lowered to consider previous application's residual available nitrate (NO) and mineralization (inorganic N), especially if there is substantial organic matter which releases its supply of sequestered N. In the spring, heavy nitrogen applications for the first two months caused changes in color, but the nitrogen response by the grass was not maintained and a decrease in color was found as the growing season progressed. Spring fertilization can increase the tiller numbers of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azole
Azoles are a class of five-membered heterocyclic compounds containing a nitrogen atom and at least one other non-carbon atom (i.e. nitrogen, sulfur, or oxygen) as part of the ring. Their names originate from the Hantzsch–Widman nomenclature. The parent compounds are aromatic and have two double bonds; there are successively redox, reduced analogs (azolines and azolidines) with fewer. One, and only one, lone pair of electrons from each heteroatom in the ring is part of the aromatic bonding in an azole. Names of azoles maintain the prefix upon reduction (e.g., pyrazoline, pyrazolidine). The numbering of ring atoms in azoles starts with the heteroatom that is not part of a double bond, and then proceeds towards the other heteroatom. Imidazole and other five-membered aromatic heterocyclic systems with two nitrogens are extremely common in nature and form the core of many biomolecules, such as histidine.

Active Ingredient
An active ingredient is any ingredient that provides biologically active or other direct effect in the diagnosis, cure, mitigation, treatment, or prevention of disease or to affect the structure or any function of the body of humans or animals. The similar terms active pharmaceutical ingredient (abbreviated as API) and bulk active are also used in medicine. The term active substance may be used to describe the effective chemical used to control bacteria or pests. Some medication products can contain more than one active ingredient. The traditional word for the active pharmaceutical agent is pharmacon or pharmakon (from , adapted from '' pharmacos'') which originally denoted a magical substance or drug. The terms active constituent or active principle are often chosen when referring to the active substance of interest in a plant (such as salicylic acid in willow bark or arecoline in areca nuts), since the word "ingredient" can be taken to connote a sense of human agency (tha ...

Propiconazole
Propiconazole is a triazole fungicide, also known as a DMI, or demethylation inhibiting fungicide due to its binding with and inhibiting the Lanosterol 14 alpha-demethylase, 14-alpha demethylase enzyme from demethylating a precursor to ergosterol. Without this demethylation step, the ergosterols are not incorporated into the growing fungal cell membranes, and cellular growth is stopped. Agriculture Propiconazole is used agriculturally as a systemic fungicide on turfgrasses grown for seed and aesthetic or athletic value, wheat, mushrooms, corn, wild rice, peanuts, almonds, sorghum, oats, pecans, apricots, peaches, nectarines, plums, prunes and lemons. It is also used in combination with permethrin in formulations of wood preserver. Propiconazole is a mixtureL. Toribio, M. J. del Nozal, J. L. Bernal, J. J. Jeménez und C. Alonso,'' J.

Fludioxonil
Fludioxonil is a synthetic phenylpyrrole chemical introduced by Ciba-Geigy (now Syngenta) in 1993 for use as a non-systemic fungicide. It is a structural analog of the natural fungicide pyrrolnitrin. It is used for the treatment of crops, particularly cereals, fruits and vegetables, and ornamental plants. It is often used in combination with another fungicide such as Cyprodinil. There was a particularly bad crop failure due to multiresistant Botrytis cinerea in Florida, ''B. cinerea'' in strawberry in Florida in 2012; in that year and many other years, fludioxonil was the only fungicide still providing any protection. Its mode of action is to inhibit transport-associated phosphorylation of glucose, which reduces mycelium, mycelial growth rate. Fludioxonil is used against ''Fusarium'', ''Rhizoctonia'', ''Alternaria'', ''Botrytis cinerea'', and ''Stromatinia cepivora''. Brand names include seed treatments: Celest, Agri Star Fludioxonil 41 ST, Dyna-shield Fludioxonil, Maxim 4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azoxystrobin
Azoxystrobin is a broad spectrum systemic fungicide widely used in agriculture to protect crops from fungal diseases. It was first marketed in 1996 using the brand name Amistar and by 1999 it had been registered in 48 countries on more than 50 crops. In the year 2000 it was announced that it had been granted UK Millennium product status. History In 1977, academic research groups in Germany published details of two new antifungal antibiotics they had isolated from the basidiomycete fungus '' Strobilurus tenacellus''. They named these strobilurin A and B but did not provide detailed structures, only data based on their high-resolution mass spectra, which showed that the simpler of the two had molecular formula C16H18O3. In the following year, further details including structures were published and a related fungicide, oudemansin A from the fungus '' Oudemansiella mucida'', whose identity had been determined by X-ray crystallography, was disclosed.

Didecyldimethylammonium Chloride
Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound used as an antiseptic/disinfectant. It causes the disruption of intermolecular interactions and the dissociation of lipid bilayers. The bacteriostatic (prevent growth) or bactericidal (kill microorganism) activity of DDAC depends on its concentration and the growth phase of the microbial population. It is a broad spectrum biocidal against bacteria and fungi and can be used as disinfectant cleaner for linen, recommended for use in hospitals, hotels and industries. It is also used in gynaecology, surgery, ophthalmology, pediatrics, OT, and for the sterilization of surgical instruments, endoscopes and surface disinfection. In mice this disinfectant was found to cause infertility and birth defects when combined with alkyl (60% C14, 25% C12, 15% C16) dimethyl benzyl ammonium chloride (ADBAC). These studies contradict the older toxicology data set on quaternary ammonia compounds which was reviewed by the U.S. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sporulation
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. In some rare cases, a diploid spore is also produced in some algae, or fungi. Under favourable conditions, the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
