Matrine ndi mtundu wa botanical fungicide.Amachokera ku mizu, zimayambira, masamba ndi zipatso za Sophora flavescens.Mankhwalawa alinso ndi mayina ena otchedwa matrine ndi nsabwe za m'masamba.Mankhwalawa ndi otsika poizoni, otsika-zotsalira, okonda zachilengedwe, ndipo angagwiritsidwe ntchito pa tiyi, fodya ndi zomera zina.

Matrine amatha kulepheretsa minyewa yapakati ya tizirombo, kutsekereza puloteni ya tizilombo, kutsekereza stomata ya tizirombo, ndi kupha tizirombo.Matrine amatha kukhudza komanso kupha poizoni m'mimba ndipo amatha kupha tizirombo tosiyanasiyana.

Matrine ndi abwino pothana ndi tizirombo toyamwa monga nsabwe za m'masamba, ndipo ali ndi zotsatira zabwino pa mbozi za kabichi, njenjete za diamondback, mbozi za tiyi, ntchentche zobiriwira, ntchentche zoyera, ndi zina zambiri. Kuphatikiza apo, mankhwalawa amakhalanso ndi zotsatira zabwino pa matenda ena, monga , chimfine, ndi mildew.

Popeza matrine ndi mankhwala ophera tizirombo opangidwa ndi zomera, mankhwala ake ophera tizirombo sachedwa.Nthawi zambiri, zotsatira zabwino zitha kuwoneka patatha masiku 3-5 mutagwiritsa ntchito.Kuti imathandizira kufulumira komanso kosatha kwa mankhwala, Iwo akhoza pamodzi ndi pyrethroid mankhwala kukhala bwino kulamulira kwambiri mbozi ndi nsabwe za m'masamba.

Kuwononga Tizirombo:

1. Tizilombo ta njenjete: Kulamulira mphutsi, njenjete zapoizoni, njenjete za m'ngalawa, njenjete zoyera, ndi mbozi zapaini nthawi zambiri zimakhala pa 2-3rd instar instar stage stage, yomwenso ndi nthawi yovuta kwambiri ya kuwonongeka kwa tizirombozi.

2. Kulamulira mbozi.Kuwongolera kumachitika pamene nyongolotsi zili ndi zaka 2-3, nthawi zambiri pakatha sabata akuluakulu aikira mazira.

3. Pa matenda a anthrax ndi miliri, matrine ayenera kupopera matenda atangoyamba kumene.

Mafomu odziwika bwino a matrine:

0.3 matrine emulsifiable concentrate, 2% matrine amadzimadzi wothandizila, 1.3% matrine amadzimadzi wothandizila, 1% matrine amadzimadzi wothandizila, 0.5% matrine amadzimadzi wothandizila, 0.3% matrine amadzimadzi agent, 2% sungunuka wothandizila, 1.5% soluble, 1. 0.3% sungunuka wothandizira.

Kusamalitsa:

1. Ndizoletsedwa kusakaniza ndi mankhwala ophera tizilombo amchere, kupewa kuyatsa kwambiri, komanso kuthira mankhwala ophera tizilombo kutali ndi nsomba, shrimp, ndi nyongolotsi za silika.

2. Matrine ali ndi vuto losamva bwino kwa mphutsi za 4-5 ndipo sizothandiza kwambiri.Kugwiritsa ntchito mankhwalawa koyambirira kuyenera kudziwidwa kuti tipewe tizilombo tating'onoting'ono.
