Ntchito ndi Kugwiritsa Ntchito Njira ya Imidacloprid

Kugwiritsa ntchito: Sakanizani 10%imidaclopridndi 4000-6000 nthawi dilution solution kupopera mbewu mankhwalawa. Mbewu zogwiritsidwa ntchito: Zoyenera ku mbewu monga kugwiririra, sesame, rapeseed, fodya, mbatata, ndi minda ya scallion. Ntchito ya wothandizira: Itha kusokoneza dongosolo lamanjenje lamagalimoto a tizirombo. Pambuyo tizirombo takumana ndi wothandizira, yachibadwa conduction wa chapakati mantha dongosolo watsekedwa, ndiyeno iwo olumala ndi kufa.

1. Kugwiritsa ntchito ndende

Imidacloprid imagwiritsidwa ntchito makamaka polimbana ndi tizirombo monga nsabwe za m'masamba, ma pear psyllids, nsabwe za m'mapichesi, whiteflies, moths roller leaf and leaf flyes. Mukamagwiritsa ntchito, sakanizani 10% imidacloprid ndi 4000-6000 times dilution solution popopera mbewu mankhwalawa, kapena sakanizani 5% imidacloprid emulsifiable concentrate ndi 2000-3000 times dilution solution.

2. Mbewu zogwiritsidwa ntchito

Pamene imidacloprid imagwiritsidwa ntchito pa mbewu monga kugwiriridwa, sesame ndi rapeseed, mamililita 40 a wothandizira amatha kusakaniza ndi mamililita 10 mpaka 20 a madzi ndikukutidwa ndi 2 mpaka 3 mapaundi a mbewu. Akagwiritsidwa ntchito pa mbewu monga fodya, mbatata, scallions, nkhaka ndi celery, ayenera kusakaniza ndi mamililita 40 a madzi ndikugwedezeka bwino ndi nthaka yopatsa thanzi musanabzale zomera.

3. Zochita za wothandizira

Imidacloprid ndi nitromethylene systemic insecticide komanso receptor ya nicotinic acetylcholine. Iwo akhoza kusokoneza galimoto mantha dongosolo la tizirombo, kuchititsa kufala kwawo chizindikiro cha mankhwala kusagwira ntchito. Pambuyo tizirombo takumana ndi wothandizira, yachibadwa conduction wa chapakati mantha dongosolo watsekedwa, ndiyeno kukhala olumala ndi kufa.

4. Makhalidwe othandizira mankhwala

Imidacloprid angagwiritsidwe ntchito poletsa kuyamwa tizirombo ndi kugonjetsedwa kwa mitundu yawo, monga planthoppers, nsabwe za m'masamba, leafhoppers, whiteflies, ndi zina zotero. Komanso, ali wabwino mofulumira kwenikweni. Kuwongolera kwakukulu kumatha kuchitika mkati mwa tsiku limodzi mutatha kupopera mbewu mankhwalawa, ndipo nthawi yotsalira imatha pafupifupi masiku 25.
