氟乐灵除草剂具有选择性强,杀草谱广,残效期长,便于机械化耕作,使用安全等优点。目前在我国东北大豆田大面积施用,防除田间杂草。为了尽快解决京郊菜区茄科、豆科、葫芦科菜田除草问题,1979年我们在十多种蔬菜田上进行了试验示范。主要在直播育苗菜田播前施药和移栽定植蔬菜田栽前或栽后缓苗后喷雾或撒施毒土处理,并混入土中。现把效果报道如下: 1.用48％氟乐灵乳油0.25—0.3斤/亩,对京郊菜田常见杂草如稗、狗尾草、马唐、画眉、藜、小藜、灰绿藜、反枝苋、凹头苋等防效显著,可达90％左右。持效期为3—4个月,一次施药,可维持整个生育期内田间不发生草荒,而且使用方便,可在播前或移栽前结合整地施药,施药后可中耕松土,不存在破坏土层降低药效的问题。和现在大量推广的除草醚相比:①成本低,按每亩用0.25斤药
Trifluralin herbicides with strong selectivity, broad spectrum herbicides, long residual period, easy mechanized farming, the use of safety and so on. Currently in China’s northeast soybean crop large area application, control weeds in the field. In order to solve as soon as possible in the suburbs of Beijing suburbs Solanaceae, Leguminosae, Cucurbitaceae field weeding problems, in 1979 we in more than 10 kinds of vegetable fields were tested. Mainly in the live nursery dish before sowing sowing and transplanting planting vegetable fields before or after planting Huanmiao spray or soil poisoning, and mixed into the soil. The results are reported as follows: 1 with 48% trifluralin 0.25-0.3 kg / mu of common vegetables on the suburb of Beijing suburbs such as barnyard grass, Setaria, crabgrass, thrush, pigweed, quinoa, Chenopodium glaucum, anti Amaranthus, Amaranthus and other significant control effect, up to 90%. Duration of 3-4 months, a pesticide application, to maintain the field throughout the growing period does not occur grass wasteland, and easy to use, before sowing or transplanting before planting with pesticides, pesticides can be cultivated in the soil, There is no problem of destroying the soil to reduce the efficacy. And now a lot of promotion of weed ethers compared: ① low cost, with 0.25 kg per acre
