Pob zeb diamondback npauj, kab ntsig kab ntsig, Spodoptera exigua, Spodoptera litura thiab thrips yog hom zaub thiab kab tsuag. Lawv rov tsim dua sai thiab ua rau muaj kev puas tsuaj loj rau cov qoob loo. Rau cov kab tsuag no, abamectin thiab emamectin ntsev feem ntau yog siv los tswj. Txawm li cas los xij, cov tshuaj tua kab no siv sijhawm ntev los tua kab thiab yooj yim los tsim kev tiv thaiv thaum siv ntev. Niaj hnub no, kuv xav qhia rau koj txog cov tshuaj tua kab uas, thaum siv ua ke nrog avermectin, tsis yog tsuas yog tua kab sai, tab sis kuj muaj kev ua tau zoo thiab tsis tshua muaj kev tiv thaiv. Qhov no yog "chlorfenapyr".
1. Mechanism ntawm kev ua
Chlorfenapyr yog ib hom tshiab ntawm pyrrole compound uas ua rau mitochondria ntawm cov hlwb hauv cov kab tsuag, rhuav tshem cov txheej txheem tsim hluav taws xob hauv cov hlwb, ua rau cov cell tsis ua haujlwm thiab thaum kawg ua rau cov kab tsuag tuag. Chlorfenapyr tua cov kab sai sai thiab zoo, tab sis muaj cov kab mob nqaim thiab siv sijhawm luv luv. Abamectin muaj cov kab mob dav dav thiab siv sijhawm ntev. Kev sib xyaw ua ke ntawm ob, ua ke nrog kev tiv thaiv thiab kev kho mob, tsis yog tsuas yog muaj kev ua haujlwm siab, tab sis kuj muaj kev cuam tshuam ntev.
2. Cov yam ntxwv tseem ceeb
(1) Broad insecticide spectrum. Nws muaj cov teebmeem tseem ceeb ntawm cov kab tsuag xws li pob zeb diamondback npauj, beet armyworm, Spodoptera litura, kab ntsig kab ntsig, nplooj yoov, psyllids, whiteflies, thrips, kab laug sab mites liab thiab lwm yam kab tsuag hauv ntau cov qoob loo xws li zaub, teb thiab txiv hmab txiv ntoo. , Flea beetles muaj cov nyhuv tua.
(2) Cov nyhuv nrawm nrawm. Chlorfenapyr muaj permeability zoo thiab kev ua haujlwm zoo. Ua ke nrog avermectin, nws tuaj yeem tua cov kab tsuag hauv 1 teev tom qab thov, thiab ncav cuag qhov kawg ntawm cov kab tsuag tuag hauv 24 teev. Kev tswj hwm kev ua haujlwm ntawm tib hnub nce mus txog ntau dua 95%, thiab kev ua tau zoo yog nce 4 zaug.
(3) Kev ua haujlwm siab thiab ua haujlwm ntev. Thaum ob qhov sib xyaw ua ke, cov nyhuv tswj yog kwv yees li 90% nyob rau hauv 1-3 hnub tom qab thov, thiab cov nyhuv yuav kav ntev. Tom qab 15 hnub ntawm daim ntawv thov, qhov ua tau zoo tseem tuaj yeem khaws cia li ntawm 80%.
(4) Nws tsis yooj yim los tsim cov tshuaj tiv thaiv. Abamectin thiab chlorfenapyr muaj cov tshuaj tua kab sib txawv. Kev sib xyaw ua ke ob yuav tsis yooj yim tsim kev tawm tsam.
3. Cov qoob loo siv tau
Feem ntau suav nrog zaub xws li kua txob, txiv lws suav, zaub qhwv, thiab zaub nplooj, cov qoob loo xws li nplej thiab pob kws, thiab txiv hmab txiv ntoo xws li lychees.
4. Tiv thaiv thiab tswj cov khoom
Pob zeb diamondback npauj, cabbage kab ntsig, beet Armyworm, Spodoptera litura, cabbage borer, cabbage aphid, leafminer, thrips thiab lwm yam zaub kab tsuag.
5. Siv thev naus laus zis
Abamectin thiab chlorfenapyr muaj kev sib koom ua ke tom qab sib tov. Nws muaj kev tswj xyuas zoo ntawm cov kab mob thrips, kab ntsig, beet armyworm, leek maggots, nplooj ntoos, borers (borers ob thiab peb), thiab Spodoptera litura.
Lub sijhawm zoo tshaj plaws rau kev siv: Siv thaum nruab nrab thiab lig theem ntawm cov qoob loo loj hlob, thaum qhov kub thiab txias qis thaum nruab hnub, kom tau txais txiaj ntsig zoo dua. (Thaum qhov ntsuas kub qis dua 22 degrees, cov tshuaj tua kab ntawm abamectin yog siab dua).
Cov kev ceev faj
(1) Cov qoob loo xws li txiv maj phaub, zucchini, iab melon, muskmelon, cantaloupe, lub caij ntuj no melon, taub dag, dai melon, thiab loofah yog rhiab heev rau chlorfenapyr thiab nquag muaj teeb meem phytotoxicity tom qab siv. Tsis txhob siv nws ua ntej 10 nplooj ntawm cov qoob loo cruciferous (cab, radish, rapeseed, thiab lwm yam) vim hais tias nws yog nquag phytotoxicity.
(2) Tsis txhob siv tshuaj tua kab thaum lub sij hawm kub kub, theem paj, lossis theem yub, vim qhov no yuav ua rau muaj phytotoxicity. Thaum Chlorfenapyr ua rau phytotoxicity, nws feem ntau yog mob phytotoxicity (cov tsos mob ntawm phytotoxicity yuav tshwm sim hauv 24 teev tom qab txhaj tshuaj). Yog hais tias phytotoxicity tshwm sim, brassinolide + amino acid foliar chiv yuav tsum tau siv sij hawm los txo nws.
