  •  本產(chǎn)品為擬南芥、油菜等植物轉(zhuǎn)化輔助試劑,是表面活性劑的一種,是NP40轉(zhuǎn)化效率的40倍以上,本產(chǎn)品為GE公司的專利產(chǎn)品(注冊商標)

         Silwet-L77高效有機硅表面活性劑,能夠極大的降低水的表面張力(水的表面張力為72.4mN/m,0.1%的Silwet-L77系列有機硅溶液的表面張力約為21mN/m),這使Silwet-L77有機硅溶液可輕易濕潤幾乎所有種類的葉面,相對于傳統(tǒng)助劑,顯著提高了在靶標生物的覆蓋面.同時,Silwet-L77有機硅助劑具有極強的耐水沖刷及滲透能力。Silwet-L77是擬南芥及其它作物常用的轉(zhuǎn)基因用表面活性劑。

    GE Silwet L-77 E表面活性劑 Silwet 77
    Kinetic是一種獨特的非離子有機硅潤濕劑/展著劑/滲透劑,用來加快農(nóng)藥吸收附著和營養(yǎng)物質(zhì)滲透進植物的葉徑。因其獨特的功能,比普通的表面活性劑使用的比率低很多。主要的有效成分為Silwet
    L-77,在技術(shù)上避免了SilwetL-77在使用上的很多缺點,如農(nóng)藥有效成分的流失,對植物蒸發(fā)作用的影響,泡沫太多,在某些PH值條件下易水解,毒性太強等缺點。
    有效成分:
    聚環(huán)醚改性聚二甲基硅氧烷;聚氧乙烯聚氧丙烯共聚物
    主要特點:
    Ø     超級的展著擴散能力
    Ø        迅速潤濕葉面,潤濕時間為14.2秒
    Ø        將藥液鎖定在葉面上不滴落,并能抗雨水沖刷
    Ø        能使藥液向上擴散,增加擴散面積
    Ø        符合環(huán)保要求
    理化性質(zhì):
    Ø        外觀:               低粘性液體
    Ø        氣味:               微有助劑氣味,無刺激性
    Ø        有效成分含量(%):    ≥99%
    Ø        PH(5%水溶液):       5.0-6.0
    Ø        比重:               1.025g/ml
    Ø        表面張力(0.1%水溶液):29達因/厘米
    Ø        接觸角(0.1%水溶液):  0
    Ø        展著性(0.1%水溶液):  7.5
    Ø        閃點:               93℃
    應用范圍:
    Ø        大豆,稻谷和蔬菜除草劑
    Ø        用于水性除草劑和芽后非選擇性除草劑特別有效Ø        植物生長調(diào)節(jié)劑
    使用方法:
    本產(chǎn)品只能用做桶混助劑使用,可提高噴霧覆蓋面,提高滲透性和降低噴霧量。在實際使用中,一定要在農(nóng)藥稀釋后才可加入,并在配藥完成后36小時內(nèi)施藥完畢。此外赤霉素用于柑橘屬作物,柑橘新鮮上市時,本品慎用.具體的使用方法如下:
    Ø        農(nóng)作物:0.05%-0.1%v/v
    Ø        草坪:  0.05%-0.125%v/v
    Ø        樹:    0.1%-0.2%v/v
    詳細介紹:      
    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 36hours.
