Njira zopewera ndikuwongolera maluwa a mtengo wa apulo atagwa

Mitengo ya maapulo pang'onopang'ono imalowa m'nthawi yamaluwa. Pambuyo pa maluwa, pamene kutentha kumakwera mofulumira, tizirombo todya masamba, tizirombo ta nthambi ndi tizirombo ta zipatso timalowa mu chitukuko chofulumira ndi kuberekana, ndipo chiwerengero cha tizirombo tosiyanasiyana chidzawonjezeka mofulumira.
Pafupifupi masiku 10 maluwa atagwa ndi nthawi yachiwiri yovuta yowononga tizirombo ta apulosi. Samalani kwambiri ndi zochitika zazikulu za tizilombo toyambitsa matenda. Chiwerengero cha anthu chikafika pa index index, njira zopewera ndi zowongolera ziyenera kuchitidwa munthawi yake.
Isanafike ndi pambuyo maluwa kugwa, makamaka fufuzani kuwonongeka udindo wa masamba, achinyamata mphukira, achinyamata zipatso ndi nthambi, moganizira red akangaude, tsamba wodzigudubuza njenjete, apulo yellow nsabwe za m'masamba, ubweya apulo nsabwe za m'masamba, nsikidzi, thonje bollworms ndi longhorn kafadala, etc. ., ndikuwona ngati pali zizindikiro zilizonse pamasamba amkati. Pali akangaude ofiira, nsabwe za m'masamba pa mphukira zazing'ono, nsikidzi zobiriwira pamwamba pa mphukira, ndikuwona ngati pali mphutsi za bollworm pa masamba aang'ono ndi zipatso zazing'ono.

Kwa mbande ndi zitsamba, yang'anani pakufufuza ngati pali mphutsi pamwamba pa nthambi ndi masamba a nthambi, ngati pali nsonga zoyera (kuwonongeka kwa nsabwe za m'masamba) pazipsera za nthambi ndi mabala, komanso ngati pali ambiri masamba wodzigudubuza njenjete mphutsi pa mitengo ikuluikulu ndi pansi. Zitosi zatsopano zokhala ngati utuchi (ngozi yachikumbu). Tizirombo tikachuluka, sankhani kupopera mankhwala molingana ndi mtundu wa tizirombo.
Ndikofunikira kudziwa kuti zipatso zazing'ono zimakhudzidwa ndi mankhwala ophera tizilombo komanso sachedwa phytotoxicity. Kupopera mbewu mankhwalawa kwa emulsifiable concentrate kukonzekera ndi otsika mankhwala ayenera kupewedwa panthawiyi. Pankhani ya kupanga, zizindikiro zenizeni zopewera ndi kuwongolera ndi miyeso panthawi yogwira ntchito ndi izi:
Pamene chiwerengero cha akangaude chikapezeka kuti chikufika pa 2 pa tsamba panthawi yoyendetsa munda, ma acaricides monga etoxazole kapena spirodiclofen akhoza kupopera kuti athetse.

 

Pamene nsabwe za m'masamba zidutsa 60%, mankhwala ophera tizilombo monga imidacloprid, Lambda-cyhalothrin kapena chlorpyrifos amatha kupopera kuti athetse nsabwe za m'masamba komanso tizilombo tonunkha, nsabwe za m'masamba ndi tizirombo ta ma scale. Pakati pawo, kupewa ndi kuwongolera nsabwe za m'masamba apulosi, pamene mawanga amapezeka m'munda, amatha kuchotsedwa ndi manja kapena kupukutidwa. Ngati zimachitika kawirikawiri, kuwonjezera kupopera mankhwala omwe atchulidwa pamwambapa panthambi za munda wonse, mizu iyeneranso kuthiriridwa ndi 1000 nthawi za 10% imidacloprid wonyowa ufa.

Ngati m'munda wa zipatso muli mphutsi zambiri za thonje, mutha kupopera mankhwala ophera tizilombo monga mchere wa emamectin ndi Lambda-cyhalothrin, omwe amathanso kuwononga tizirombo ta lepidopteran monga ma pear heartworms ndi ma roller amasamba.
Ngati mutapeza dzenje lachimbudzi pamtengo, gwiritsani ntchito syringe nthawi yomweyo kubaya 1 mpaka 2 ml ya chlorpyrifos kapena 100-fold solution ya chlorpyrifos kapena cypermethrin mudzenje lachimbudzi, ndikusindikiza dzenjelo ndi dothi. Samalani kuti musabaye jekeseni woyambirira kuti muteteze ndende kuti ikhale yokwera kwambiri. Kuchuluka ndi kuyambitsa phytotoxicity.
