米泉旱田地区以旋花（俗称撤撤秧、喇叭花、田草秧子等）为害高粱、玉米最为严重。在水稻地区以鸭娃草（俗称）为害最凶。以上两种杂草如用人工防除,每亩地需10个以上的劳动日,有的达15个劳动日,占每亩稻田用工总数的70％以上,造成了除草极为紧张的局面,对其他农活影响很大。 米泉农科所使用了天津公私合营化学试剂三厂出品的2·4·5—T钠盐进行了对旋花和鸭娃草的防除试验。 2·4·5—T钠盐对旋花的防除效果最好,对旱田其他杂草稍有防除抑制作用,在旱田使用也很方便。该药对高粱和玉米等禾本科作物并无不良影响。
Miquan dryland areas to Convolvulaceae (commonly known as withdrawal of seedlings, daffodils, field grass seedlings, etc.) for sorghum, corn is the most serious. Duck grass in the rice area (commonly known as) the most vicious damage. The above two kinds of weeds, such as the use of artificial control, the need for more than 10 days per acre labor day, and some up to 15 labor days, accounting for more than 70% of the total rice paddies, resulting in a very tight weeding situation, other Farming has a great impact. Miquan Agricultural Science and Technology Co., Ltd. used the 2.4.5-T sodium salt produced by Tianjin Public-Private Partnership Chemical Reagent Factory No. 3 for the prevention and control of Convolvulus and Duckweed. 2.4.5-T sodium salt has the best control effect on Convolvulaceae, has a slight control effect on other weeds in the dry field, and is also very convenient to use in dry fields. This medicine has no adverse effect on gramineous crops such as sorghum and corn.
