Kugwiritsa Ntchito Chlorempenthrin

ChlorempenthrinNdi mtundu watsopano wa mankhwala ophera tizilombo otchedwa pyrethroid omwe amagwira ntchito bwino kwambiri komanso ali ndi poizoni wochepa, womwe umathandiza kwambiri udzudzu, ntchentche ndi mphemvu. Uli ndi mphamvu ya nthunzi yambiri, kusinthasintha kwabwino komanso mphamvu yakupha, ndipo liwiro la tizilombo toyambitsa matenda limachepa mofulumira, makamaka popopera ndi kufukiza.

Njira yogwiritsira ntchito

1. Kuletsa tizilombo ta thonje

(1) Kupewa ndi kulamulira nyongolotsi za thonje: kugwiritsa ntchito mankhwala pamene mazira akuyamwa kwambiri, 10% bifenthrin kirimu 23 ~ 40ml pa mu ya madzi 50 ~ 60kg kupopera, 7 ~ 10d mankhwalawo atatha, ali ndi mphamvu yabwino yophera tizilombo komanso kuteteza mphukira. Mlingo uwu ungagwiritsidwenso ntchito kulamulira nyongolotsi za thonje. Nthawi yoyenera yopewera ndi kuchiza ndi m'badwo wachiwiri ndi wachitatu wa kuyamwa mazira, ndipo m'badwo uliwonse umachiritsidwa kawiri.

(2) Kupewa ndi kuchiza nthata za masamba a thonje: Ngati nthata zagwiritsidwa ntchito pa nthawi yomwe zayamba kufalikira, 10% kirimu wa 30 ~ 40ml pa mu ya madzi 50 ~ 60kg, nthawi yotsala ya pafupifupi masiku 12, ikhozanso kuchiza nthata za thonje, nyongolotsi za m'mphepete, nyongolotsi za masamba, thrips, ndi zina zotero. (monga ngati zaperekedwa popewa ndi kuchiza nthata za thonje, mlingo wake ukhoza kuchepetsedwa ndi theka).

2. Lawani tizilombo towononga mitengo ya zipatso

(1) Kupewa ndi kuchiza nyongolotsi za peachworm: Pakani mankhwala pamene mazira akuyamwa kwambiri, pamene chiwerengero cha zipatso za mazira chafika pa 0.5% ~ 1%, gwiritsani ntchito 10% bifenthrin emulsion 3300 ~ 4000 nthawi yamadzimadzi. Kupopera katatu mpaka kanayi mu nyengo yonse kungathandize kulamulira kuwonongeka kwake, ndipo nthawi yotsalayo ndi pafupifupi masiku 10.

(2) Kupewa ndi kuchiza nthata za masamba a apulo: apulo isanayambe kapena itatha kuphuka, ikakula ndipo ngati nthata zayamba, tsamba lililonse likafika pa avareji ya nthata ziwiri, ikani mankhwala, ndipo thirani ndi kirimu wa 10% nthawi 3300 ~ 5000. Pankhani ya nthata zochepa pakamwa, nthawi yotsala inali masiku 24 mpaka 28. Ingagwiritsidwenso ntchito kuwongolera okumba masamba ndi nthata za masamba ofiira pamitengo ina ya zipatso.

3. Lamulani tizilombo towononga masamba

(1) Kulamulira ntchentche zoyera: Poyamba kuoneka ntchentche zoyera, kuchuluka kwa tizilombo sikukwera kwambiri.

(2) Ponena za mutu/chomera, mlingo wake ndi: nkhaka ndi tomato zomwe zalimidwa m'nyumba yobiriwira zokhala ndi zosakaniza zogwira ntchito 2 ~ 2.5g pa mu imodzi ya 50kg yothira pamadzi, yotsegulidwa yolimidwa ndi zosakaniza zogwira ntchito 2.5 ~ 4g pa mu imodzi ya 50kg yothira pamadzi, imatha kuwongolera bwino kuwonongeka kwake mkati mwa masiku 15. Ngati kuchuluka kwa tizilombo kuli kwakukulu, mphamvu yowongolera ya mlingo womwewo siikhazikika.

(3) Kupewa ndi kuchiza nsabwe za m'masamba: Pakani mankhwala nthawi yomwe imachitika, gwiritsani ntchito mafuta oyeretsera a bifenthrin 10% nthawi 3000 ~ 4000 nthawi yamadzimadzi, amatha kuwongolera kuwonongeka, nthawi yotsala ya pafupifupi masiku 15. Mlingo uwu ukhozanso kuwongolera tizilombo tosiyanasiyana todya masamba, monga mphutsi za kabichi, njenjete za diamondi ndi zina zotero.
