Varimi vebindu vari kutsvaga zvinotsiva mishonga yezvipembenene.Vamwe vari kunetsekana nezve mhedzisiro yekemikari chaiyo pahutano hwavo.
Vamwe vari kuchinja vachiitira hanya zvinhu zvinokuvadza zviri munyika yakavapoteredza.Kune ava varimi, biopesticides inogona kuve yakapfava asi inoshanda imwe nzira.
Mishonga yeBiopesticides inonziwo mishonga yezvipembenene yakasikwa kana yebhayoloji.Iwo kazhinji haana muchetura kune zvisina kunanga zvipenyu uye zvakatipoteredza.
Bacillus thuringiensis uye Spinosad maviri akajairika biopesticides.Kunyanya, iwo ma microbial insecticides.
Kazhinji, marudzi eBacillus thuringiensis ane twupukanana asi Spinosad yakawedzera kuwanda.
Chii chinonzi Microbial Insecticides?
Microbe izita pfupi rezvipembenene.Izvi zvipenyu zvidiki zvekuti hatigone kuzviona nemaziso.
Panyaya yemishonga inouraya tupukanana, tiri kutaura nezveutachiona husingakuvadzi kuvanhu, asi hunouraya kune tupukanana.
Mushonga wemushonga unouraya zvipembenene ndiwo utachiona pachahwo.Inogona kunge iri mabhakitiriya, fungi, protozoa, microbe-carrying nematodes, kana kunyange utachiona.
Bacillus thuringiensis (Bt) inongowanikwa muvhu, mvura, uye pane chirimwa.Saccharopolyspora spinosa (Spinosad) inogara muvhu zvakare.
Mashandisirwo eMicrobial Insecticide?
Kufanana nevanhu nezvirimwa zvavo zvemubindu, zvipembenene zvipembenene zvinotapurwa neutachiona.Mishonga inouraya zvipembenene inotora mukana weutera uhwu.
Izvo zvine huwandu hwakanyanya hwehutachiona hunowanikwa mune zvakasikwa uye hunozivikanwa kuti hunokanganisa tupukanana twupukanana.Utachiona hunobata chipembenene.
Somugumisiro, chipembenene chacho chinorwara zvokutadza kuramba chichidya kana kutadza kubereka.
Bt inokanganisa nhanho yegonye (caterpillar) yemapoka akawanda ezvipembenene.Kana makonye, sehornworms, achidya Bt, anotanga kuvira muura hwavo.
Muchetura wainoburitsa unokonzeresa kuti makonye arege kudya uye anofa mazuva mashoma gare gare.
Mhando dzakasiyana dzeBt dzinonanga mapoka ezvipembenene.Bt var.kurstaki inotarisa makonye (butterfly uye moth larvae), semuenzaniso.
Bt var.israelensis inonangidzira nhunzi dzinobhururuka, kusanganisira umhutu.Iva nechokwadi chekusarudza mhando chaiyo yeBt yechipembenene chako.
Spinosad ndeye yakawedzera-spectrum microbial insecticide.Inobata makonye, vanochera mashizha, nhunzi, thrips, zvipembenene, uye dandemutande.
Spinosad inoshanda nekurwisa sisitimu yetsinga kana zvipembenene zvazvidya.Kufanana neBt, zvipembenene zvinomira kudya uye kufa mazuva mashomanana mushure.
