1 accurately calculate the dose based on soil and climatic conditions, grass love Nicosulfuron determined amount of medication to the amount of quasi-chemical control area to area medication, accurate dilution, uniform portable sprayers spraying, do not re-spray, spray does not leak, does not arbitrarily increase drug concentration and spraying times.
Two strictly proper spraying of liquid medication scientifically formulated to determine the period, it is necessary to consider the sensitive period of weeds, for good control effect, but also to choose seasonal crops resistant to strong, safe time Xiacha crop spraying . 3-5 leaf stage of corn for resistance Nicosulfuron strongest, safest medication at this time. If because of the weather and other reasons, the 6-leaf stage of corn after the medication, as directed spray, pharmaceutical avoid touching the heart of corn leaves. General 2-leaf stage of corn leaf stage before and 10 after the drug-sensitive, not medication. Meanwhile, the solution should be accurate dilution, mix well before spraying.
3 application techniques to improve the level of strict rules to guide farmers Phytocide poor performance out of the existing old-fashioned manual sprayers, the introduction of good performance, high efficiency, low cost, a new sprayer. Currently there are better performance Shandong Wish Plant Protection Machinery Co., Ltd. produces WS-16P type sprayer and Shandong Huasheng Pesticide Co., Ltd. production Tarzan-18AC backpack sprayers duster machine. As nicosulfuron herbicide is super efficient, re-spray, drip, it is likely to cause local agent concentration is too large to produce injury. In addition, before each medication must ensure that sprayer clean, avoid the other Yaoxie corn injury caused by pesticide residues.
In addition, naphthalic anhydride with corn seed coating can reduce Nicosulfuron with organophosphate insecticides effect caused by the injury.
