Cov kab mob tseem ceeb hauv txoj kev loj hlob ntawm raspberries yog qia rot, willow bat npauj thiab raspberry perforating npauj. Cov kab tsuag tseem ceeb yog: willow bat moth thiab raspberry perforating npauj.
1. qia rot
(1) Cov tsos mob:
Kev puas tsuaj rau raspberry basal ceg feem ntau tshwm sim ntawm cov tua tshiab. Ua ntej, ib qho tsaus grey scalded lesion tshwm los ntawm tshav ntuj sab ntawm cov tua tshiab ze rau hauv av, txog 1.5-2.5 cm ntev thiab 06-1.2 cm dav. Kev nthuav dav sai mus rau ib puag ncig, tus kab mob maj mam xim av, qhov chaw ntawm qhov txhab tshwm sim dub me ntsis ntawm qhov sib txawv, thiab xylem ua xim av thiab necrotic. Nrog rau kev nthuav dav ntawm cov kab mob, nplooj thiab petioles tig daj thiab wither, thiab thaum kawg tag nrho cov nroj tsuag tuag. Qhov kub thiab txias thiab lub caij los nag yog lub caij nyoog ntawm tus kab mob, uas feem ntau tshwm sim hauv peb thaj av txij lub Rau Hli mus txog Lub Yim Hli.
(2) Txoj kev tiv thaiv
① Ntxuav lub vaj nyob rau lub caij nplooj zeeg, txiav cov kab mob thiab hlawv lawv.
② Txau 500 npaug ntawm thiophanate-methyl, lossis 500 npaug ntawm 40 feem pua ethylphosphine, lossis 500 zaug ntawm Fumeishuang thaum pib ntawm lub Tsib Hlis mus txog Lub Xya Hli.
③ Xaiv cov kab mob uas tiv taus ntau yam. Hais txog kev hais lus, dub raspberries muaj kab mob ntau dua li liab raspberries, thiab zoo dua rau kev cog qoob loo nyob rau yav qab teb cheeb tsam.
2. Npauj Npaim
(1) Cov tsos mob:
Nws yog cov kab tsuag tseem ceeb uas ua rau muaj kev puas tsuaj rau raspberries thiab cuam tshuam rau lub xyoo thib ob yield. Cov larvae pib nteg rau hauv cov tua tshiab thaum ntxov Lub Xya Hli (txij thaum lub Tsib Hlis mus txog rau Lub Rau Hli hauv qee thaj chaw), thiab cov borer nkag yog 40-60 cm deb ntawm av, thiab feem ntau ntawm lawv noj downward. Willow bat moths feem ntau tawm mus nibble ntawm sab phloem ntawm kab noj hniav, thiab feem ntau ntawm lawv noj nyob ib ncig ntawm ib lub lim tiam. Cov tom sawdust thiab quav yog glued ua ke nrog lo lo ntxhuav, thiab tsob ntoo txuas nrog lub voj voog, thiab nws yuav tsis poob rau lub sijhawm ntev. Cov ceg raug tsim txom tau yooj yim tawg thiab qhuav thiab tuag.
(2) Txoj kev tiv thaiv
① Txiav cov ceg puas thiab hlawv ua ntej cov neeg laus tshwm.
② Thaum lub sijhawm ua haujlwm ntawm thawj lub hnub qub larvae los ntawm nruab nrab-Tsib Hlis txog rau Lub Yim Hli, 2.5 feem pua deltamethrin 2000-3000 lub sij hawm tuaj yeem txau, uas tuaj yeem ua tiav cov txiaj ntsig zoo.
3. Raspberry Piercing Moth
(1) Cov tsos mob:
Liab raspberries muaj teeb meem ntau dua rau liab raspberries. Nyob rau hauv lub caij nplooj zeeg, lawv cocoon thiab overwinter nyob rau hauv lub hauv paus ntawm basal ceg. Thaum lub caij nplooj ntoos hlav, lawv nce cov tua tshiab, dhuav rau hauv cov tua, thiab tom qab noj cov nroj tsuag sib tw, lawv tho rau hauv cov tua tshiab, ua rau cov tua tshiab tuag. Tom qab cov neeg laus tshwm sim, lawv nteg qe nyob rau hauv lub paj thaum yav tsaus ntuj, thiab larvae pib noj berries, thiab sai sai hloov mus rau lub hauv paus rau overwintering.
(2) Txoj kev tiv thaiv
① Ntxuav lub vaj tom qab khaws cov txiv hmab txiv ntoo thaum lub caij nplooj zeeg lig.
② Txau 80 feem pua dichlorvos 1000 zaug tshuaj los yog 2.5 feem pua deltamethrin 3000 zaug tshuaj thaum lub caij nplooj ntoos hlav tua cov larvae.
