Diamondback moth, cov kab pab tub kab ntoo, cov tub rog beetworm, spodoptera litura, thiab thrips yog cov kab thiab teb cov qoob loo. Lawv rov ua dua tshiab thiab ua rau muaj kev puas tsuaj loj rau cov qoob loo. Rau cov tsuag tsuag no, kev ua phem thiab emamectin belzoate feem ntau siv rau kev tswj hwm. Txawm li cas los xij, cov tshuaj tua kab no siv sijhawm ntev los tua cov kab, thiab ntev- siv tau yooj yim ua rau muaj kev tawm tsam yooj yim. Niaj hnub no, kuv xav qhia kev tua tsiaj. Thaum thov ua ke nrog abamectin, nws tsis yog tsuas yog tua kab sai, tab sis kuj tseem muaj kev ua tau zoo thiab tsis muaj feem xyuam rau kev tiv taus. Qhov no yog "chlorfenapyr".
1. Mechanism ntawm Kev Ua
Chlorfenapyr yog lub pyrrole tshiab uas ua rau ntawm cov txheej txheem cellular mitochondria nyob rau hauv lub hlwb, yog li ua rau cell tsis ua hauj lwm thiab kawg ua rau kev tuag ntawm cov kab tsuag. Chlorfenapyr tua kab sai thiab zoo, tab sis nws muaj qhov nqaim kab ntsig spectrum thiab ib lub sijhawm luv luv ntawm cov nyhuv. Anamectin muaj qhov dav nti tawm thiab ntev ntev ntawm cov nyhuv. Kev sib xyaw ntawm ob, nrog ob qho tib si tiv thaiv thiab curative cuam tshuam, tsis tsuas yog muaj txiaj ntsig zoo tab sis kuj tseem ntev ntev ntawm cov nyhuv.
2. Cov yam ntxwv tseem ceeb
(1) dav hom tshuaj ntsuam. Nws muaj cov nyhuv tseem ceeb ntawm pob txha caj dab, beet cov tub rog Artworms, cov kab ke ntawm cov kab ke, Psyllids, cov zaub qhwv, cov qoob loo nyoos, cov qoob loo teb, thiab cov ntoo txiv ntoo. Nws kuj muaj qee cov nyhuv tua ntawm cov kab tsw ntxhiab tsw yoov thiab dev mub.
(2) Zoo sai - ua yeeb yam khoom. Chlorfenapyr muaj kev lom zem zoo heev thiab qhov system conductivity. Thaum sib xyaw nrog kev ua phem, nws tuaj yeem tua cov kab tsuag tsis pub dhau 1 teev, ncav cuag kev tswj hwm ntawm ntau dua 95% rau tib hnub, thiab kev ua tau zoo nce los ntawm 4 zaug.
(3) kev ua tau zoo thiab ntev ntev. Kev sib xyaw ntawm ob qho tuaj yeem ua tiav cov nyhuv tswj tau txog 90% tsis pub dhau 90-3 hnub tom qab thov nyiaj ntev. Txawm 15 hnub tom qab daim ntawv thov, kev ua tau zoo tseem tuaj yeem nyob ntawm 80%.
(4) Kev pheej hmoo qis ntawm kev loj hlob. Abamectin thiab chlorfenapyr muaj cov tshuaj tua kab sib txawv, yog li lawv cov dej sib tov tsis muaj tsawg yuav ua rau kev txhim kho ntawm kev tiv taus.
3. Cov qoob loo muaj feem xyuam
Nws yog feem ntau muaj cov zaub xws li kua txob, txiv lws suav, cabbages thiab cov zaub nplooj xws li nplej thiab cov txiv hmab txiv ntoo xws li Lychees.
4. Tswj cov hom phiaj:
Diamondback npauj kab laum, zaub qhwv cov tub rog, cov tub rog ntoo, cabbage webworms, zaub pob, pov tseg thiab lwm yam zaub.
5. Daim Ntawv Thov Tshuab
Kev sib xyaw ua ke ntawm kev ua phem thiab chlorfenapyr muaj cov nyhuv tseem ceeb, thiab cov kab ntsig zoo, cov tub rog ntoo ntsuab, tryporza litulas) thiab spodoptera litura.
Cov Ntawv Zoo Tshaj Plaws: Nws muaj txiaj ntsig zoo dua thaum tau thov nyob rau hauv nruab nrab thiab lig kev loj hlob theem ntawm cov qoob loo thiab thaum qhov kub thiab txias qis dua nruab hnub. (Anamectin muaj cov tshuaj tua kab ntau dua thaum qhov kub nyob hauv qab 22 degree.)
Cov kev ceev faj
(1) Cov qoob loo xws li dib liab, lub caij ntuj sov squas, muskmels, cantaloupes, thiab licksows, thiab Luffas tau tshwm sim tom qab daim ntawv thov; Cov qoob loo cog qoob loo (Suav cabbages, rapeseeds, thiab lwm yam) yog nquag rau phytotoxicity yog tias thov ua ntej lawv muaj 10 nplooj, yog li tsis siv nws.
(2) Tsis txhob siv cov tshuaj tua kab thaum lub caij sov, thaum lub sijhawm ua paj lossis lub caij cog qoob loo, raws li phytotoxicity kuj tseem muaj tshwm sim. Thaum phytotoxicity yog tshwm sim los ntawm chlorfenapyr, nws feem ntau mob phytotoxicity (cov tsos mob yuav tshwm li tsis pub dhau 24 teev tom qab thov). Yog tias phytotoxicity tshwm sim, siv tam sim tooj dag + amino acid -} raws foliar fertilizer rau kev pab.
