嚴格控制農藥用量保證食品安全

　　目(mu)前我國(guo)農藥(yao)產(chan)量(liang)很高(gao)，針對農藥(yao)在使(shi)用過程(cheng)中存在的(de)(de)一(yi)些問(wen)題，有效的(de)(de)解(jie)決措施勢在必(bi)行。合(he)理施用農藥(yao)，嚴格遵守國(guo)家法(fa)律法(fa)規(gui)，嚴格控制藥(yao)劑的(de)(de)加水(shui)(shui)倍數，掌握(wo)好配(pei)藥(yao)技(ji)術的(de)(de)好壞，生產(chan)出安全、對人畜無害的(de)(de)農業產(chan)品，提(ti)高(gao)人們的(de)(de)生活(huo)水(shui)(shui)平。

　　農(nong)(nong)藥(yao)(yao)(yao)(yao)(yao)用(yong)量影響病蟲的(de)防治效(xiao)果，在配藥(yao)(yao)(yao)(yao)(yao)時，加水(shui)過多，影響藥(yao)(yao)(yao)(yao)(yao)效(xiao)，加水(shui)過少，不僅浪費農(nong)(nong)藥(yao)(yao)(yao)(yao)(yao)，還可能引起藥(yao)(yao)(yao)(yao)(yao)害和病蟲抗藥(yao)(yao)(yao)(yao)(yao)性(xing)的(de)產(chan)生。在配制(zhi)乳劑(ji)和可濕性(xing)粉(fen)劑(ji)時，要先用(yong)少量的(de)水(shui)將藥(yao)(yao)(yao)(yao)(yao)劑(ji)配成(cheng)漿糊狀，然后再(zai)緩緩加入所需要的(de)水(shui)，并不斷攪拌，使農(nong)(nong)藥(yao)(yao)(yao)(yao)(yao)充分溶解，才能發(fa)揮農(nong)(nong)藥(yao)(yao)(yao)(yao)(yao)的(de)物理性(xing)能。

　　在(zai)用(yong)水(shui)時(shi)，要選用(yong)清水(shui)，污(wu)水(shui)中雜質較(jiao)多(duo)，容易堵塞噴(pen)頭。抓住施用(yong)農藥(yao)(yao)害(hai)蟲(chong)(chong)(chong)(chong)(chong)(chong)的防治(zhi)適期(qi)(qi)，農業上許多(duo)害(hai)蟲(chong)(chong)(chong)(chong)(chong)(chong)的發育一般要經過卵、幼蟲(chong)(chong)(chong)(chong)(chong)(chong)、蛹、成(cheng)蟲(chong)(chong)(chong)(chong)(chong)(chong)四個階段，在(zai)昆蟲(chong)(chong)(chong)(chong)(chong)(chong)學上稱之為完全(quan)變態(tai)類型(xing)。幼蟲(chong)(chong)(chong)(chong)(chong)(chong)期(qi)(qi)是(shi)(shi)害(hai)蟲(chong)(chong)(chong)(chong)(chong)(chong)取食生長時(shi)期(qi)(qi)，防治(zhi)效(xiao)果好，農藥(yao)(yao)易滲(shen)近害(hai)蟲(chong)(chong)(chong)(chong)(chong)(chong)體(ti)壁，取食量不是(shi)(shi)很大，幼蟲(chong)(chong)(chong)(chong)(chong)(chong)期(qi)(qi)、成(cheng)蟲(chong)(chong)(chong)(chong)(chong)(chong)期(qi)(qi)是(shi)(shi)用(yong)藥(yao)(yao)防治(zhi)的關鍵時(shi)期(qi)(qi)。

　　噴藥(yao)(yao)過多(duo)，浪費農藥(yao)(yao)，噴藥(yao)(yao)過少或(huo)不均(jun)勻，不周(zhou)到，防治(zhi)效果不好(hao)，需要重(zhong)視噴藥(yao)(yao)質量，在(zai)(zai)(zai)保證質量的(de)前提下(xia)，達(da)到多(duo)、快、好(hao)、省地(di)消滅病蟲害。應(ying)在(zai)(zai)(zai)無風的(de)陰天或(huo)晴(qing)天進行，將要下(xia)雨的(de)天氣不宜施(shi)藥(yao)(yao)。如在(zai)(zai)(zai)有(you)風的(de)天氣施(shi)藥(yao)(yao)，應(ying)注意風向(xiang)，如果風速過大，應(ying)停止施(shi)藥(yao)(yao)。
