在直播水稻中,有些一年生及多年生杂草(特别是稗草),目前常规的除草剂往往难以防除,或需使用很高的剂量才能得以控制。为此,水稻种植者迫切需要有高效低用量的除草剂,以能确保水稻丰收。 KIH2023系日本组合化学公司开发的,用于直播稻的新颖芽后处理除草剂。该药剂对稻田中广范围的禾本科杂草和阔叶杂草具有卓效。其最大的商业潜力为能选择性地防除稗草,且用量极低,应用范围广。 In direct seeding rice, some annual and perennial weeds, especially barnyardgrass, are often difficult to control with conventional herbicides or require very high doses to be controlled. To this end, rice growers urgently need to have efficient and low dosage of herbicides, in order to ensure rice harvest. KIH2023 is a novel post-emergent budding herbicide developed by Japan Kabushiki Kaisha for direct seeding rice. The agent is effective against a wide range of grass weeds and broad-leaved weeds in paddy fields. Its maximum commercial potential is that it can selectively control barnyardgrass, and its dosage is extremely low, so it has wide application range.
