呋喃丹(Furadan),通用名卡巴呋喃(Carbofuradan),是一种广谱性内吸杀虫剂,并有触杀和胃毒作用。据国外报道可用于40多种作物300多种害虫和线虫,并有促进作物生长发育的效能。在土壤中半衰期为30-60天,在植物叶子中只存留8天左右,无残留,在人畜体内不积累。1978年铜山农药厂和沈阳化工研究院用进口的75%母粉采用包衣法研制成3%呋喃丹颗粒剂,经1979年部分地区试验,用以防治农作物害虫药效明显。在林业上使用较少。1980—1981年我们以杨苗害虫为对象进行小区试验,施药方法是选用二年根当年条畅苗田三亩,于5月23日、6月2日、6月13日三个不同时间,距杨苗5厘米一侧开沟深3—5厘米埋药,施药后立即浇水,每次分40、30、20、10斤/亩
Furadan, commonly known as Carbofuradan, is a broad-spectrum systemic insecticide with contact and stomach toxicity. According to foreign reports can be used for more than 40 kinds of crops more than 300 kinds of pests and nematodes, and to promote the effectiveness of crop growth and development. In the soil half-life of 30-60 days, leaves in plants only survive for about 8 days, no residue, no accumulation in human and animal body. In 1978, Tongshan Pesticide Factory and Shenyang Chemical Research Institute made 75% of the imported mother powder by coating method into 3% carbofuran granules. After being used in some areas in 1979, the pesticide used to control pests of crops was obviously effective. Less used in forestry. From 1980 to 1981, we used Yang Miao pests as the test object for community trials. The method of application was to use three mu of Phyllostachys praeparata in two years. At three different times on May 23, June 2 and June 13, 5 cm away from Yang Miao side ditch 3-5 cm deep buried drugs, watering immediately after application, each time 40,30,20,10 pounds / mu
