注意：近期市場(chǎng)上出現(xiàn)假冒SILWET L-77一般為NP40等表面活性物質(zhì)，外觀和SILWET L-77相似，但轉(zhuǎn)化效率非常低，最高的轉(zhuǎn)化效率也只有SILWET L-77的1/40，假冒SILWET L-77一般只能提供10ML分裝產(chǎn)品，我公司有10ML原裝和35ML原裝，并可提供相關(guān)進(jìn)口證明材料，我公司也可提供相關(guān)轉(zhuǎn)化實(shí)驗(yàn)服務(wù)，費(fèi)用請(qǐng)電話咨詢。
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.
