Thermostable alpha-amylase Introduction: thermostable alpha- amylase is made from bacillus lickeniformis by adopting deeply-submerged fermentation, and it is a liquid. It is usually used to make amylase, alcohol, beer, monosodium glutamate, and also be used in such fields as bio-pharmaceutics and liquefaction. The quality of thermostable amylase meets qb/b2306f¼1997. 1. Characteristics: + type of action: thermostable amylase is an endonuclease which can immediately hydrolyze amylum, soluble dextrin and low polysaccharide. It also can immediately reduce the viscocity of gelling starch, then gelling starch are hydrolyzed into dextrin, dextrose and maltose. + the effects of ph on amylase activity and amylase stability of this product: when ph ranges from 5.0 to 10.0, it is stable. Its favorable ph ranges from 5.0 to 8.0. Its most favorable ph ranges from 5.5 to 7.0. ª its favorable temperature is above 90f¦. When it is continuously spouted and liquefied, the temperature could range from 100f¦ to 105f¦. Appearance: brown liquid Amylase activity: 20, 000u/ml and 25, 000u/ml Amylase livability: 90% of amylase can live more than 3 months. 2. Definition and recommended quantity At 70fpc and ph6.0, the quantity of amylase used to liquefy 1 mg soluble amylum into dextrin is regarded as 1 amylase activity unit. Of 1t amylum, it is better to use 200-400ml thermostable amylase. 3. Packing This product is packed in plastic drums or in paper cartons without toxicity, 25kgs/drum or 30kgs/cardboard drum.

Nicosulfuron Common name: nicosulfuron Cas no. 111991-09-4 Molecular formula: c15h18n6o6s Activity: herbicide Ingredient: 95% tc Formulation: 4% sc, 75% wdg Application: Nicosulfuron Selective post-emergence control in maize of annual grass weeds, broad-leaved weeds and perennials grass weeds. Nicosulfuron is absorbed by the leaves of treated plants and translocated to the meristematic tissue causing growth inhibition, discoloration, necrosis and, eventually, plant death. The product is most effective against grasses when applied between emergence and tillering. Broadleaf weeds are most effectively controlled when treated at the 2-3-leaf stage. Split applications can improve the efficacy of the product. Nicosulfuron is rainfast within six hours. Dupont recommends the use of adjuvants such as non-ionic surfactants or crop oil concentrates to enhance the activity of its granular product. Nicosulfuron has no residual activity, being quickly metabolised by plants. Nicosulfuron shows high selectivity to maize, but treatment of maize crops with some soil insecticides sensitises the crop to nicosulfuron, resulting in crop damage. Dupont and isk report that nicosulfuron is safe to soybeans planted in rotation with maize.

Silway 240 is polyther trisiloxane spray adjuvant. In aqueous solutions, it gives super spreading and does dramatically reduce surface tension. Silway 240 could significantly reduce the surface tension of agricultural aqueous mixtures. At concentrations low as 0.1 percent, Silway 240 spray adjuvant redces surface tension below 22mN/m, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves. Silway 240 spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations. 7 Key Features: * Superspreading for exceptional spray coverage of crop and plant surfaces * Up to 70% spray volume reduction to lower water use and application costs * Excellent penetration providing better pesticide uptake and efficacy * Better spray treatment adhesion on crop and plant surfaces * Rainfastness to lower pesticide wash-off and waste * Lower use levels than non-silicone surfactants * Nonionic Typical Applications: * Crop protection products * Herbicides * Insecticides * Fungicides * Nutrients and plant * Growth regulators
