三唑类杀菌剂大幅增长○吡虫啉等化学合成的新烟碱类杀虫剂可能成为第四大类杀虫剂○磺酰脲类、咪唑啉酮类等抑制乙酰乳酸合成酶的除草剂前景看好 1998年世界农药的销售额已超过310亿美元。据美国业内人士的预测,世界农药市场的增长速度比较缓慢,预计到2001年,世界农药的销售额将为338.3亿美元。其中,杀菌剂的销售额为59.8亿美元,杀虫剂为87.9亿美元,除草剂为160.1亿美元,杀线虫剂、熏蒸剂为5.15亿美元,植物生长调节剂7亿美元;1996年以后新出现的抗虫害作物、耐除草剂
Triazole biocides have grown dramatically ○ Neonicotinyl insecticides chemically synthesized by imidacloprid may become the fourth largest class of insecticides ○ Sulfonylurea and imidazolinone herbicides that inhibit acetolactate synthase are promising In 1998, the sales of pesticides in the world exceeded 31 billion U.S. dollars. According to predictions by industry insiders in the United States, the growth rate of the world’s pesticide market is relatively slow. It is estimated that by 2001, the world’s pesticide sales will be 33.83 billion US dollars. Among them, the sales of fungicides was 5.98 billion U.S. dollars, the insecticides were 8.79 billion U.S. dollars, the herbicides were 16.01 billion U.S. dollars, the nematicides and fumigants were 515 million U.S. dollars, and the plant growth regulators were 700 million U.S. dollars; Appeared pest-resistant crops, herbicide-tolerant
