M'chilimwe ndi autumn, kutentha kwakukulundi heavymvula, yomwe ndi yabwinotkubereka ndi kukula kwa tizirombo.Mankhwala ophera tizirombo achikale amalimbana kwambiri ndipo alibe mphamvu zowongolera.Lero, ndikuyambitsa mankhwala ophera tizilombo, omwe ndi othandiza kwambiri ndipo amatha mpaka masiku 30.Izi pawiri chiphunzitso ndiEmamectinBenzo +Lufenuron.

Kodi emamectin benzoate ndi chiyani?

Emamectinbenzoatendi theka-maantibayotiki kwambiri yogwira tizilombo apanga pa maziko aABamectin B1.Ikhoza kunenedwa kuti ndi yokwezeraAbamectin.Magulu awiri atsopano amawonjezedwa mwachinyengo kumapeto onse a mankhwala ake.Ndi methylamino ndi benzoic acid, kotero dzina lonse ndiMethylaminoAbamectinBenzoate.

Ntchito yake yophera tizilombo ndiyoposa katatu kuposaAbamectin, makamaka pamene kutentha kupitirira madigiri 25, ntchito yowononga tizilombo imakhala yochuluka, yomwe siimangokhaliraAbamectin, komanso akuwonetsa ubwino wowonjezera magulu ena.Kuphatikiza apo,EmamectinBenzoate ali wabwino zokhudza zonse madutsidwe, akhoza mwamsanga odzipereka ndi zomera zimayambira ndi masamba, anasamutsidwa mwa zomera thupi, ndipo pang'onopang'ono kudziunjikira mu epidermis.Tizilombo tikawononga mbewuyo, timapanga chigawo chachiwiri chopha tizilombo, motero chimakhala kwa nthawi yayitali.

Kodi Lufenuron ndi chiyani?

Lufenuron ndi m'badwo waposachedwa wa mankhwala ophera tizilombo tambiri, otakata komanso ochepa omwe amalowa m'malo mwa urea.Amagwiritsidwa ntchito makamaka poletsa mphutsi za tizilombo kuti zisakanike kuti zikwaniritse cholinga chopha tizilombo.Amagwiritsidwa ntchito makamaka poyipitsa m'mimba.Amagwiritsidwa ntchito kwambiri poletsa zoboola tsinde zosiyanasiyana, njenjete za diamondback ndi ndiwo zamasamba.Tizilombo toyambitsa matenda monga mbozi ndi nyongolotsi za beet ndizodziwika kwambiri poyang'anira zogudubuza masamba a mpunga.

Tizilombo tikakumana ndi medicament ndikudya masamba ndi medicament, pakamwa pawo patatha maola awiri, kudyetsa kudzayimitsidwa kuti asiye kuvulaza mbewu.Chiwopsezo cha tizilombo takufa chidzafikiridwa m'masiku 3-5, ndipo nthawi yogwira ntchito imatha kufika masiku oposa 25.Imakhala ndi zotsatira zofatsa pa tizilombo topindulitsandim'badwo waposachedwa wa mankhwala ophera tizilombo.

3. Zabwino mwachangu zotsatira

Chifukwa chowonjezera cha lufenuron, chilinganizochi chimapangitsa kusowa kwa emamectin benzoate.Tizilombo tikadya, pakamwa pakamwa pakamwa patatha maola awiri, kudyetsa kumayimitsidwa, potero kuyimitsa kuwonongeka kwa mbewu.

4. Chitetezo chabwino

Njirayi ndi yotetezeka kwambiri ku mbewu ndipo ingagwiritsidwe ntchito nthawi iliyonse ya mbewu.Mpaka pano, ndondomekoyi ilibe phytotoxicity, yomwe ndi yotetezekar toalimi ndi ogawa.
