Kodi mungapewe bwanji tizilombo ku chimanga? Kodi mankhwala abwino kwambiri oti mugwiritse ntchito ndi ati?

Chimanga ndi chimodzi mwa mbewu zomwe zimafala kwambiri. Alimi onse akuyembekeza kuti chimanga chomwe amabzala chidzakhala ndi zokolola zambiri, koma tizilombo ndi matenda amachepetsa zokolola za chimanga. Ndiye chimanga chingatetezedwe bwanji ku tizilombo? Kodi mankhwala abwino kwambiri ogwiritsira ntchito ndi ati?
Ngati mukufuna kudziwa mankhwala oti mugwiritse ntchito popewa tizilombo, choyamba muyenera kumvetsetsa tizilombo tomwe tili pa chimanga! Tizilombo tomwe timapezeka pachimanga ndi monga nyongolotsi, ma mole crickets, thonje la bollworm, akangaude, two-pointed noctuid moth, thrips, aphids, noctuid moths, ndi zina zotero.

1. Ndi mankhwala ati omwe amagwiritsidwa ntchito polimbana ndi tizilombo ta chimanga?
1. Spodoptera frugiperda nthawi zambiri imatha kulamulidwa ndi mankhwala monga chlorantraniliprole, emamectin, ndi njira monga kupopera, kutchera chambo cha poizoni, ndi kuwononga nthaka.
2. Polimbana ndi nyongolotsi ya thonje, mankhwala ophera tizilombo toyambitsa matenda monga Bacillus thuringiensis, emamectin, chlorantraniliprole ndi mankhwala ena angagwiritsidwe ntchito panthawi yobereka mazira.
3. Nthata za akangaude zitha kuthetsedwa ndi abamectin, ndipo tizilombo tomwe timakhala pansi pa nthaka ndi thrips nthawi zambiri timathetsedwa ndi cyantraniliprole ngati mankhwala ophera mbewu.
4. Kupaka mbewu, oxazine ndi zina zopaka mbewu zimalimbikitsidwa popewa ndi kulamulira nyongolotsi. Ngati kuwonongeka kwa tizilombo pansi pa nthaka kwachitika mtsogolo,chlorpyrifos, phoxim, ndibeta-cypermethriningagwiritsidwe ntchito kuthirira mizu. Ngati kuwonongeka kuli kwakukulu, mutha kupopera beta-cypermethrin pafupi ndi mizu ya chimanga madzulo, ndipo imakhala ndi zotsatira zina!
5. Pofuna kupewa matenda a thrips, tikukulangizani kugwiritsa ntchito acetamiprid, nitenpyram, dinotefuran ndi njira zina zowongolera!
6. Pofuna kuletsa nsabwe za chimanga, alimi amalimbikitsa kugwiritsa ntchito 70% imidacloprid nthawi 1500, 70% thiamethoxam nthawi 750, 20% acetamiprid nthawi 1500, ndi zina zotero. Zotsatira zake ndi zabwino kwambiri, ndipo kukana konse kwa nsabwe za chimanga sikoopsa!
7. Kupewa ndi kulamulira njenjete za noctuid: Pofuna kupewa ndi kulamulira tizilombo toyambitsa matenda, tikulimbikitsidwa kugwiritsa ntchito zosakaniza izi, monga emamectin,indoxacarb, lufenuron, chlorfenapyr, tetrachlorfenamide, beta-cypermethrin, cotton boll polyhedrosis virus, ndi zina zotero! Ndibwino kugwiritsa ntchito kuphatikiza kwa zosakaniza izi kuti mupeze zotsatira zabwino!
