公眾對農產品質量安全日益關注，加上國家提出農藥用量零增長和綠(lv)色防(fang)控達(da)到30%的(de)(de)目標，生物農藥被(bei)寄(ji)予厚望，其(qi)推廣和應用也遇到了極大的(de)(de)發展機遇。
施用(yong)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)農(nong)(nong)藥(yao)(yao)(yao)有(you)利于保護天敵，維護生(sheng)(sheng)(sheng)態(tai)平衡，減少(shao)(shao)病蟲(chong)(chong)害(hai)發生(sheng)(sheng)(sheng)和(he)農(nong)(nong)藥(yao)(yao)(yao)使用(yong)量，且大部分沒(mei)有(you)安全間隔期，無須擔心殘留超標，是高端農(nong)(nong)產(chan)品的(de)(de)(de)可(ke)靠藥(yao)(yao)(yao)劑，市(shi)場前(qian)景非常廣闊(kuo)。但(dan)在推(tui)廣應用(yong)過程中卻面(mian)臨(lin)不少(shao)(shao)成長的(de)(de)(de)煩惱(nao)，防治面(mian)積也沒(mei)有(you)大的(de)(de)(de)突(tu)破(po)。原因何在？正如不少(shao)(shao)從業者所說，生(sheng)(sheng)(sheng)物(wu)(wu)(wu)農(nong)(nong)藥(yao)(yao)(yao)藥(yao)(yao)(yao)效(xiao)相對較(jiao)慢，用(yong)藥(yao)(yao)(yao)成本較(jiao)高，使用(yong)相對麻煩，而農(nong)(nong)民往(wang)往(wang)追求(qiu)立竿見影(ying)的(de)(de)(de)效(xiao)果，不太愿意接受生(sheng)(sheng)(sheng)物(wu)(wu)(wu)農(nong)(nong)藥(yao)(yao)(yao)。再加上目前(qian)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)農(nong)(nong)藥(yao)(yao)(yao)品種不多，一(yi)些農(nong)(nong)作物(wu)(wu)(wu)重要病蟲(chong)(chong)害(hai)缺少(shao)(shao)高效(xiao)防治的(de)(de)(de)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)農(nong)(nong)藥(yao)(yao)(yao)，有(you)的(de)(de)(de)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)農(nong)(nong)藥(yao)(yao)(yao)防效(xiao)不穩定，尤其是活體微(wei)生(sheng)(sheng)(sheng)物(wu)(wu)(wu)制劑質量不穩定，藥(yao)(yao)(yao)效(xiao)受環境影(ying)響(xiang)較(jiao)大，同(tong)時價格(ge)不菲，市(shi)場拓展困難不小，這甚至導致部分生(sheng)(sheng)(sheng)物(wu)(wu)(wu)農(nong)(nong)藥(yao)(yao)(yao)企業有(you)生(sheng)(sheng)(sheng)產(chan)許(xu)可(ke)證但(dan)并沒(mei)有(you)真正生(sheng)(sheng)(sheng)產(chan)營銷。
如(ru)何加快推(tui)廣應用(yong)、讓(rang)生物(wu)農(nong)(nong)(nong)藥(yao)(yao)(yao)發(fa)揮更大(da)作(zuo)(zuo)用(yong)？不(bu)少專家認為，一方(fang)面應該(gai)加強生物(wu)農(nong)(nong)(nong)藥(yao)(yao)(yao)研(yan)(yan)發(fa)創新(xin)(xin)，揚長(chang)(chang)避短，另一方(fang)面也需要加強扶持和引導。應篩選(xuan)高(gao)活(huo)性(xing)生物(wu)農(nong)(nong)(nong)藥(yao)(yao)(yao)有效(xiao)(xiao)(xiao)成(cheng)分，強化制劑產(chan)品(pin)(pin)創新(xin)(xin)，研(yan)(yan)制出能延(yan)長(chang)(chang)田間(jian)藥(yao)(yao)(yao)效(xiao)(xiao)(xiao)時間(jian)和提高(gao)藥(yao)(yao)(yao)效(xiao)(xiao)(xiao)穩(wen)定性(xing)的產(chan)品(pin)(pin)；加強研(yan)(yan)發(fa)化學農(nong)(nong)(nong)藥(yao)(yao)(yao)與生物(wu)農(nong)(nong)(nong)藥(yao)(yao)(yao)的混配產(chan)品(pin)(pin)。同(tong)時，加大(da)生物(wu)農(nong)(nong)(nong)藥(yao)(yao)(yao)及(ji)(ji)綜(zong)合防(fang)治(zhi)措(cuo)施的宣(xuan)傳普及(ji)(ji)，讓(rang)農(nong)(nong)(nong)民知道，生物(wu)農(nong)(nong)(nong)藥(yao)(yao)(yao)使(shi)用(yong)選(xuan)擇(ze)時機很重要，比如(ru)天敵使(shi)用(yong)應在前期害蟲(chong)種群量少、密度低的時候使(shi)用(yong)，不(bu)能當作(zuo)(zuo)應急手(shou)段。
針(zhen)對(dui)企業生(sheng)(sheng)(sheng)產(chan)積(ji)極性不(bu)高(gao)的(de)(de)現(xian)狀(zhuang)，應該對(dui)生(sheng)(sheng)(sheng)物(wu)(wu)農(nong)藥(yao)加大(da)補貼(tie)力度，給生(sheng)(sheng)(sheng)物(wu)(wu)農(nong)藥(yao)登(deng)記開綠燈，縮短審批時(shi)間和(he)減免登(deng)記費用，鼓勵引(yin)導生(sheng)(sheng)(sheng)物(wu)(wu)農(nong)藥(yao)發(fa)展(zhan)。農(nong)業部應該擴大(da)生(sheng)(sheng)(sheng)物(wu)(wu)農(nong)藥(yao)的(de)(de)推(tui)廣應用試點，探索新的(de)(de)補貼(tie)方式，采取以合作社為平臺、經(jing)銷(xiao)商(shang)為紐帶、統(tong)防統(tong)治(zhi)組織(zhi)為載(zai)體等方式規(gui)范(fan)補貼(tie)，推(tui)動生(sheng)(sheng)(sheng)物(wu)(wu)農(nong)藥(yao)更好地發(fa)展(zhan)。
