水稻田化学除草在日本开展得很好,在热带水稻生产国家也越来越受到重视。Noda(1980)报道各种稗草,特别是稗,在日本和东南亚国家是一种很重要的杂草,其它一年生杂草如异型莎草、碎米莎草等也是稻田的主要杂草。一种能有效防除这些一年生杂草的新型除草剂莎稗磷(代号为Hoe 30374)已在赫司特公司开发研制成功,并已于前几年在各种不同的条件下进行了广泛的试验。本文报道有关试验结果。 Chemical weed control in paddy fields is well developed in Japan and more and more important in tropical rice-producing countries. Noda (1980) reported that various barnyardgrass, especially barnyardgrass, is a very important weed in Japan and Southeast Asian countries. Other annual weeds such as Shaped Cyperaceae and Brassica oleracea are also the main weeds in paddy fields. A new herbicide, barnyard grass (codenamed Hoe 30374) that is effective in controlling annual weeds has been developed at Hoechst and has undergone extensive testing in a number of different conditions in previous years . This article reports on the test results.
