Wamaluwa kufunafuna m'malo ochiritsira mankhwala.Ena akuda nkhawa ndi zotsatira za mankhwala enaake pa thanzi lawo.
Ena akusintha chifukwa chodera nkhawa zinthu zoipa zimene zikuchitika padzikoli.Kwa wamaluwa awa, biopesticides ikhoza kukhala njira yabwino koma yothandiza.
Mankhwala ophera tizilombo amatchedwanso mankhwala achilengedwe kapena achilengedwe.Kaŵirikaŵiri sakhala ndi poizoni kwa zamoyo zomwe sitinazipeze komanso chilengedwe.
Bacillus thuringiensis ndi Spinosad ndi mankhwala awiri ophera tizilombo.Makamaka, ndi tizilombo toyambitsa matenda.
Nthawi zambiri, mitundu ya Bacillus thuringiensis imakhala yeniyeni ndi tizirombo pomwe Spinosad ndi yotakata kwambiri.
Kodi ma Microbial Insecticides ndi chiyani?
Microbe ndi dzina lalifupi la tizilombo toyambitsa matenda.Izi ndi zamoyo zazing'ono kwambiri moti sitingathe kuziwona ndi maso.
Pankhani ya tizilombo toyambitsa matenda, tikukamba za tizilombo toyambitsa matenda omwe alibe vuto kwa anthu, koma amapha tizilombo towononga tizilombo.
Zomwe zimagwiritsidwa ntchito mu tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda.Zitha kukhala mabakiteriya, bowa, protozoa, nematode zonyamula tizilombo toyambitsa matenda, ngakhalenso ma virus.
Bacillus thuringiensis (Bt) amapezeka mwachilengedwe m'nthaka, m'madzi, ndi pamalo omera.Saccharopolyspora spinosa (Spinosad) imakhalanso munthaka.
Kodi Tizilombo Tizilombo Tizigwira Ntchito Bwanji?
Mofanana ndi anthu ndi zomera zawo za m’munda, tizilombo timakhala ndi tizilombo toyambitsa matenda.Tizilombo toyambitsa matenda timagwiritsa ntchito mwayi wofooka uku.
Amakhala ndi tizilombo tating'onoting'ono tomwe timapezeka m'chilengedwe ndipo timadziwika kuti timawononga tizilombo tosiyanasiyana.Tizilombo toyambitsa matenda timadya tizilombo.
Zotsatira zake, tizilombo timadwala kwambiri kuti tipitirize kudya kapena kulephera kubereka.
Bt imakhudza gawo la mphutsi (mbozi) lamagulu angapo a tizilombo.Mbozi, ngati nyongolotsi, zikadya Bt, zimayamba kufufuma m'matumbo awo.
Poizoni zomwe zimatulutsa zimapangitsa kuti mbozizi zisiye kudya ndipo zimafa patatha masiku angapo.
Mitundu yeniyeni ya Bt imayang'ana magulu a tizirombo.Bt ndi.kurstaki amalimbana ndi mbozi (gulugufe ndi njenjete), mwachitsanzo.
Bt ndi.israelensis amalimbana ndi mphutsi zouluka, kuphatikizapo udzudzu.Onetsetsani kuti mwasankha mitundu yoyenera ya Bt ya tizilombo toyambitsa matenda.
Spinosad ndi mankhwala ophera tizilombo tosiyanasiyana.Zimakhudza mbozi, omba masamba, ntchentche, thrips, kafadala, ndi akangaude.
Spinosad imagwira ntchito powononga dongosolo lamanjenje pomwe tizirombo tadya.Monga Bt, tizirombo timasiya kudya ndikufa patatha masiku angapo.
