產(chǎn)品詳情

詳細(xì)信息(中文)：
產(chǎn)品特性:
殺線蟲劑棉隆熏蒸性硫代異硫氰酸甲酯類殺線蟲劑，并兼治真菌、地下害蟲和雜草；又名必速滅。常溫條件下貯存穩(wěn)定，遇濕則分解。對(duì)魚毒性中等，對(duì)蜜蜂無毒害。用途:制劑有98~100%微粒劑和75%可濕性粉劑?？捎糜诿绱?、溫室、育種室、盆載植物基質(zhì)和大田等土壤處理。在土壤中分解出有毒的異硫氰酸甲酯、甲醛和硫化氰等；這些分解物能有效地防治為害花生Chemicalbook、蔬菜、煙草、茶、果樹、林木等作物的多種線蟲和土傳病害。每公頃用有效成分60~75千克，撒施或溝施可防治短體虱、矮化虱、紐帶屬、劍屬、根結(jié)屬、胞囊屬、莖屬、等紅蟲。對(duì)土壤昆蟲、真菌和雜草也有防治效果。藥劑施入土壤后，受土壤濕度、溫度和土壤結(jié)構(gòu)影響較大；為保證藥效，土壤溫度應(yīng)保持在6℃以上，土壤含水量保持在40%以上。棉隆對(duì)魚有毒，水田應(yīng)慎用。
化學(xué)性質(zhì)?：
純品為白色針狀結(jié)晶，無氣味，m.p.99.5℃（分解）（104～105℃）。蒸氣壓400×10-6Pa。易溶于丙酮、氯仿；稍溶于乙醇、苯；難溶于醚、四氯化碳；25℃時(shí)在水中溶解度為0.12%，溫水中溶解度稍有提高。水溶液中易分解，溫度在45℃以上分解加快，影響藥劑效果；遇強(qiáng)酸、強(qiáng)堿易分解。
用途：
1.廣譜性農(nóng)藥。具有熏蒸作用的殺線蟲劑，在土壤中分解出異硫氰酸甲酯、甲醛和硫化氫，對(duì)根瘤線蟲、莖線蟲、異皮線蟲有殺滅作用。此外還有殺蟲、殺菌和除草作用，因此能兼治土壤真菌、地下害蟲和藜屬雜草，如馬鈴薯絲核菌、土杠磷翅目昆蟲Chemicalbook、叩頭蟲、五月金龜甲的幼蟲等。用98%微粒劑750～900g/100m2砂土、900～1050g/100m2黏土做土壤處理，撒施或溝施，可防治蔬菜、花生線蟲病。用75%可濕性粉劑1125g/100m2，可防治馬鈴薯根線蟲病。
2.土壤熏蒸劑，硫代異硫氰酸甲酯類殺線蟲劑，并兼治真菌、地下害蟲和雜草，又名必速滅。該品在土壤中分解生成甲胺基甲基二硫代氨基甲酸酯，并進(jìn)一步生成異硫氰酸甲酯。能有效地防治線蟲和土壤真菌，如猝倒病菌、絲核病菌、鐮刀菌等，還能抑制許多雜草生長(zhǎng)。棉隆對(duì)棉花黃枯萎病有較好的防治效果。
3.用作殺菌劑

Product features:

Nematode insecticide Cottonseed fumigating methyl thiisothiocyanate nematocide, and also for the treatment of fungi, underground pests and weeds; Also known as swift destruction. Store stably at room temperature, decompose when wet. It is moderately toxic to fish and harmless to bees. USES: the preparation has 98~100% microparticle agent and 75% wettable powder. It can be used for soil treatment such as seedbed, greenhouse, breeding room, basin-bearing plant matrix and field. Toxic methyl isothiocyanate, formaldehyde and cyanide were decomposed in the soil. These decomposition products can effectively prevent and control various nematodes and soil-borne diseases of peanut crops such as Chemicalbook, vegetables, tobacco, tea, fruit trees and trees. With 60~75 kg of active ingredients per hectare, spraying or ditching can prevent and control short body louse, dwarf louse, bristles, rhizopus, cysts, stems and other red insects. It is also effective against soil insects, fungi and weeds. After pesticide was applied to soil, it was greatly affected by soil moisture, temperature and soil structure. To ensure the efficacy, the soil temperature should be kept above 6℃ and the soil moisture content above 40%. Cottontail is poisonous to fish, and should be used with caution in paddy fields.

Chemical properties:

Pure white acicular crystal, odorless, M.P. 99.5℃ (decomposition) (104 ~ 105℃). The vapor pressure is 400 times 10-6 pA. Soluble in acetone and chloroform; Slightly soluble in ethanol and benzene; Insoluble in ether and carbon tetrachloride; The solubility in water was 0.12% at 25℃, and slightly increased in warm water. It is easy to decompose in aqueous solution, and the decomposition speeds up when the temperature is above 45℃, which affects the effect of the agent. Strong acids and bases decompose easily.

USES:

1. Broad-spectrum pesticides. Nematocide with fumigation can decompose methyl isothiocyanate, formaldehyde and hydrogen sulfide in soi
