1.用(yong)(yong)量(liang)要適(shi)宜，不(bu)能隨意加大用(yong)(yong)量(liang)。植物(wu)(wu)生長調節劑是一(yi)類與植物(wu)(wu)激素具(ju)有(you)相似(si)生理和生物(wu)(wu)學效應的(de)物(wu)(wu)質(zhi)，不(bu)能過量(liang)使(shi)用(yong)(yong)。一(yi)般每畝用(yong)(yong)量(liang)只需幾克或(huo)幾毫(hao)升。有(you)的(de)農戶總(zong)怕用(yong)(yong)量(liang)少了沒有(you)效果(guo)，隨意加大用(yong)(yong)量(liang)或(huo)使(shi)用(yong)(yong)濃度(du)，這樣做(zuo)不(bu)但不(bu)能促進植物(wu)(wu)生長，反而會使(shi)其(qi)生長受到抑(yi)制，嚴(yan)重(zhong)的(de)甚至導(dao)致(zhi)葉片畸形、干枯脫落、整株死亡(wang)。
2.不(bu)能(neng)(neng)隨(sui)意(yi)混用(yong)。很多菜農(nong)在使(shi)用(yong)植(zhi)物(wu)(wu)生(sheng)長調節劑(ji)時，為圖(tu)省事，常將其(qi)隨(sui)意(yi)與(yu)化肥(fei)(fei)、殺蟲(chong)劑(ji)、殺菌劑(ji)等混用(yong)。植(zhi)物(wu)(wu)生(sheng)長調節劑(ji)與(yu)化肥(fei)(fei)、農(nong)藥等物(wu)(wu)質能(neng)(neng)否混用(yong)，必須在認真閱(yue)讀使(shi)用(yong)說明(ming)并經(jing)過(guo)試(shi)驗后才能(neng)(neng)確(que)定，否則不(bu)僅達(da)不(bu)到促進生(sheng)長或保(bao)花保(bao)果、補充肥(fei)(fei)料(liao)的作(zuo)用(yong)，反而會(hui)因混合不(bu)當出現藥害。比(bi)如：乙烯(xi)利藥液通常呈酸性(xing)(xing)(xing)，不(bu)能(neng)(neng)與(yu)堿性(xing)(xing)(xing)物(wu)(wu)質混用(yong)；胺鮮(xian)酯(zhi)遇堿易分解(jie)，不(bu)能(neng)(neng)與(yu)堿性(xing)(xing)(xing)農(nong)藥、化肥(fei)(fei)混用(yong)。
3.使(shi)(shi)用(yong)(yong)方法要得當。有(you)(you)的菜農在使(shi)(shi)用(yong)(yong)植(zhi)物生(sheng)長調(diao)節(jie)劑前，常常不認真(zhen)閱讀使(shi)(shi)用(yong)(yong)說明，而是將植(zhi)物生(sheng)長調(diao)節(jie)劑直(zhi)接(jie)兌水使(shi)(shi)用(yong)(yong)。是否能直(zhi)接(jie)兌水一(yi)定要看清楚(chu)，因為有(you)(you)的植(zhi)物生(sheng)長調(diao)節(jie)劑不能直(zhi)接(jie)在水中(zhong)溶解，若不事先配制成(cheng)母液(ye)后再(zai)配制成(cheng)需要的濃度，藥(yao)劑很難混(hun)勻，會影響使(shi)(shi)用(yong)(yong)效(xiao)果。因此(ci)，使(shi)(shi)用(yong)(yong)時(shi)一(yi)定要嚴格按照使(shi)(shi)用(yong)(yong)說明稀釋。
4.生(sheng)長(chang)調(diao)(diao)節(jie)劑(ji)不(bu)能(neng)(neng)代替肥(fei)料(liao)(liao)施用(yong)(yong)。生(sheng)長(chang)調(diao)(diao)節(jie)劑(ji)不(bu)是植(zhi)(zhi)物(wu)(wu)營養物(wu)(wu)質，只能(neng)(neng)起調(diao)(diao)控生(sheng)長(chang)的作用(yong)(yong)，不(bu)能(neng)(neng)代替肥(fei)料(liao)(liao)使(shi)(shi)用(yong)(yong)，在水肥(fei)條件不(bu)充足的情(qing)況下，噴施過多的植(zhi)(zhi)物(wu)(wu)生(sheng)長(chang)調(diao)(diao)節(jie)劑(ji)反(fan)而有(you)害。因此(ci)，在發現(xian)植(zhi)(zhi)物(wu)(wu)生(sheng)長(chang)不(bu)良時(shi)，首(shou)先(xian)要(yao)加強施肥(fei)澆(jiao)水等管理，在此(ci)基(ji)礎上使(shi)(shi)用(yong)(yong)生(sheng)長(chang)調(diao)(diao)節(jie)劑(ji)才(cai)能(neng)(neng)有(you)效地(di)發揮其作用(yong)(yong)。
5.植(zhi)物生長調節劑屬于農藥類產(chan)品(pin)，產(chan)品(pin)包裝必須(xu)有正(zheng)規”農藥三證“，標示帶為黃色。
6.嚴(yan)格按(an)照說明書使用(yong)，做好防(fang)護措施，防(fang)止對人、畜及引用(yong)水安全造成影響。
