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

Chimanga ndi chimodzi mwa mbewu zofala kwambiri.Alimi onse akuyembekeza kuti chimanga chomwe amabzala chidzakhala ndi zokolola zambiri, koma tizirombo ndi matenda zimachepetsa kukolola kwa chimanga.Ndiye kodi chimanga chingatetezedwe bwanji ku tizilombo?Kodi mankhwala abwino kwambiri oti mugwiritse ntchito ndi ati?
Ngati mukufuna kudziwa kuti ndi mankhwala ati omwe mungagwiritse ntchito kuti mupewe tizilombo, muyenera kumvetsetsa kaye zomwe tizirombo timadya chimanga!Tizilombo tomwe timawononga chimanga ndi monga ma cutworms, crickets, bollworms, akangaude, njenjete za noctuid, thrips, aphid, njenjete za noctuid, etc.

1. Ndi mankhwala ati omwe amagwiritsidwa ntchito polimbana ndi tizilombo ta chimanga
1. Spodoptera frugiperda imatha kuwongoleredwa ndi mankhwala monga chlorantraniliprole, emamectin, ndi njira monga kupopera mbewu mankhwalawa, kutchera nyambo zapoizoni, ndi dothi lapoizoni.
2. Poyang'anira mphutsi za thonje, mankhwala a Bacillus thuringiensis, emamectin, chlorantraniliprole ndi mankhwala ena angagwiritsidwe ntchito panthawi yoweta mazira.
3. Kangaude amatha kutetezedwa ndi abamectin, ndipo tizirombo tapansi panthaka ndi thrips zimatha kutetezedwa ndi cyantraniliprole ngati chithandizo cha mbewu.
4. Kuthira njere, oxazine ndi mavalidwe ena ambewu amalangizidwa kuti apewe ndi kuwononga nyongolotsi.Ngati kuwonongeka kwa tizilombo tapansi panthaka kumachitika pambuyo pake,chlorpyrifosphoxim, ndibeta-cypermetrinangagwiritsidwe ntchito kuthirira mizu.Ngati kuwonongeka kuli kwakukulu, mukhoza kupopera beta-cypermethrin pafupi ndi mizu ya chimanga madzulo, ndipo imakhala ndi zotsatira zake!
5. Pofuna kupewa thrips, tikulimbikitsidwa kugwiritsa ntchito acetamiprid, nitenpyram, dinotefuran ndi kulamulira kwina!
6. Pofuna kuthana ndi nsabwe za chimanga, ndi bwino kuti alimi agwiritse ntchito 70% imidacloprid nthawi 1500, 70% thiamethoxam 750 nthawi, 20% acetamiprid nthawi 1500, ndi zina zotero. Zotsatira zake ndi zabwino kwambiri, ndipo kukana kwathunthu kwa nsabwe za chimanga sikuli koopsa!
7. Kupewa ndi kuwongolera njenjete za noctuid: Pofuna kupewa ndi kuwongolera tizilombo, tikulimbikitsidwa kugwiritsa ntchito zosakaniza izi, monga emamectin,indoxacarb, lufenuron, chlorfenapyr, tetrachlorfenamide, beta-cypermethrin, thonje boll polyhedrosis virus, etc.!Ndibwino kugwiritsa ntchito zosakaniza izi kuti mukhale ndi zotsatira zabwino!
