注意：近期市场上出现假冒SILWET L-77一般为NP40等表面活性物质，外观和SILWET L-77相似，但转化效率非常低，最高的转化效率也只有SILWET L-77的1/40，假冒SILWET L-77一般只能提供10ML分装产品，我公司有10ML原装和35ML原装，并可提供相关进口证明材料，我公司也可提供相关转化实验服务，费用请电话咨询。
Silwet L-77 is a chemical mixture of polyalkyleneoxide modified heptamethyltrisiloxane (84%) and allyloxypolyethyleneglycol methyl ether (16%). It is an essential infiltration media ingredient for all Agrobacterium-based transformations of Arabidopsis and other plants.10 mL and 35 mL are sufficient quantity to prepare 33 L and 115 L of vacuum infiltration medium when used at the recommended rate of 0.03%, v/v, respectively.
SILWET L-77 is a unique surfactant designed to improve the spreading and wetting properties of pesticide spray mixes. SILWET L-77 utilizes unique organosilicone chemistry which provides the most complete coverage possible. SILWET L-77 can improve cuticular penetration of plant surfaces by the spray mix. Optimum application and resultant effects can be influenced by many factors. Consequently, it is recommended that careful observation of the spray deposit be made and adjuvant rates adjusted accordingly. Applications should be made to ensure thorough coverage without excessive run-off.

GENERAL PRODUCT INFORMATION
(1) SILWET L-77 contains organosilicone surfactants designed to provide superior wetting and coverage.
(2) SILWET L-77 can improve water penetration of hard to wet soils and provide more uniform distribution of applied moisture.
(3) SILWET L-77 is generally compatible with pesticides and fertilizer solutions.
(4) SILWET L-77 may cause excessive foam if not properly added to the spray tank. To minimize foam generation, add SILWET L-77 to the tank after all other ingredients are added. If foaming is still a concern, add an antifoaming agent, such as FOAMBUSTER or COMBAT PLUS to the tank prior to adding SILWET L-77.
(5) Do not allow spray mixes containing SILWET L-77 to sit over 36 hours.
