普施特(原名普杀特)是大豆田优秀除草剂,经黑龙江垦区几年试验、示范和大面积使用证明,可防除多种禾本科草和阔叶草,且使用方便,可在播前进行混土处理,或在播后苗前进行土壤处理以及在苗后早期进行茎叶处理,均有较好的杀草效果,而且对大豆安全。目前已成为黑龙江垦区大豆田除草剂的主要品种之一,使用面积还在不断扩大。但在使用中应注意以下几点:一、根据轮作计划选择使用普施特在土壤中的残效期较长,施用过的地块第二年不宜种植油菜、水稻、高粱及白菜、辣椒、茄子、萝卜等,种植甜菜至少要间隔两年以上。可以种大豆、小麦,大麦、玉米。为此,各地在使用普施特时,一定要根据轮作计划考虑下年作物,在一年多熟地区,则更不能忽视。二、根据防除对象选择施药方法如果防除蓼、苋、茼麻、香薷、藜、龙葵、水棘针、豚草等阔叶杂草,以土壤处理效果较好;防除苍耳和稗,狗尾、牛筋等禾本科草,以苗后早期处理效果好。对铁觅无效。土壤处理时,墒情要好或施药
Pu Site (formerly known as universal kill special) is an excellent soybean crop herbicides, the Heilongjiang Reclamation years of testing, demonstration and large-scale use of proof, to prevent a variety of grass and broadleaf grass grass, and easy to use, can be sown before sowing Mixed soil treatment, or after sowing before sowing soil treatment and stems and leaves in the early post-emergence foliar treatment, have a better herbicide effect, and the safety of soybeans. Has become one of the main varieties of soybean field herbicide in Heilongjiang reclamation area, the use of area is still expanding. However, in use should pay attention to the following points: First, according to the rotation plan to choose Pst in the soil, the longer the residual effect, the second year of the plots should not be planted rape, rice, sorghum and cabbage, pepper, eggplant , Radish, etc., planting sugar beet more than two years at least intervals. Can grow soybean, wheat, barley, corn. For this reason, when using Putbus around the world, we must consider the crops under the rotation according to the rotation plan. In more than one year, more crops can not be ignored. Second, according to the control object selection method of application If the prevention and control Polygonum, amaranth, Abutilon theoxia, Quinoa, Solanum nigrum, ragweed and other broad-leaved weeds, soil treatment is better; control Xanthium and barnyardgrass, Dog tail, tendon grass and other grasses to seedlings early treatment effect is good. Look for iron invalid. Soil treatment, soil moisture or application
