Lub qe ntawm cov yeeb ncuab ntawm raspberries yog dawb, 0.35 - 0.5 hli hauv qhov loj me. Lawv cov larvae muaj lub ntsej muag nkhaus, tseem dawb, nrog lub taub hau daj daj, ntev txog 3.5 hli. Qhov me me ntawm tus menyuam dev ncav cuag 2, 5 - 3 mm, los ntawm dawb lawv maj mam hloov mus ua daj -xim av.
Lub caij ntuj no ntawm cov tib neeg tsis paub qab hau yuav tshwm sim hauv qab nplooj poob, hauv txheej txheej av. Lawv tawm ntawm lawv thaj av thaum lub Plaub Hlis lig lossis thaum ntxov Tsib Hlis, sai li sai tau thaum qhov kub tau nce siab tshaj 13 degrees (txiv pos nphuab pib loj tuaj tib lub sijhawm).
Thaum xub thawj, cov kab mob parasites pub rau ntawm nplooj, uas lawv zom tawm ntau qhov, tom qab uas lawv txav mus rau lub paj thiab pib noj tam sim ntawd lawv cov ntsiab lus. Hauv qhov (ib qho hauv txhua tus), poj niam, uas nws muaj peev xwm muaj txog 50 lub qe, tso qe; poj niam gnaw pedicels thiab npog lub qe nrog lawv cov quav. Los ntawm cov qe 6 - 7 hnub tom qab, cov kab menyuam tsis zoo rov qab los, noj tsuas yog cov ntsiab lus ntawm cov paj rau 20 - 25 hnub (thiab ntawm no yog tus tub ntxhais kawm thaum kawg ntawm lawv txoj kev loj hlob). 7 - 9 hnub tom qab, kab pib tshwm (kwv yees li Lub Xya Hli, hauv ib nrab ntawm nws) thiab pib pub mis ntxiv rau ntawm nplooj raspberry.
Thaum huab cua sov poob mus rau 10 - 12 degrees nrog qhov pib ntawm lub Cuaj Hli, cov kab tsis zoo mus rau lub caij ntuj no hauv cov khib nyiab thiab cov av.
Yuav ua li cas kom tshem tau cov cab
Raspberry weevil larvae ua zaub mov rau kab yoov tshaj cum, hoverfly larvae thiab kab hauv av. Thiab cov kab menyuam kis los ntawm braconids.
Thaum tiv thaiv kab tsuag, nws yog ib qho tseem ceeb heev kom sau cov ntoo seem nrog nplooj poob thiab tom qab ntawd hlawv lawv. Cov av tau cog tsis yog hauv lub caij nplooj zeeg xwb, tab sis tseem nyob rau lub caij nplooj ntoo hlav thaum ntxov. Txiav cov txiv pos nphuab thaum kawg ntawm kev sau qoob kuj tseem yuav ua rau tuag ib feem ntawm cov kab tsuag raspberry yog tias cov qoob loo qoob loo loj tuaj nyob ze.
Thaum cog cov txiv hmab txiv ntoo, nws tseem yog qhov tseem ceeb kom paub tias nws tsis pom zoo kom cog txiv pos nphuab nyob ib sab ntawm raspberries, vim tias lawv muaj kab tsuag ntau.
Txau nrog tshuaj tua kab ntawm tshuaj tsiav tshuaj lossis daws cov tshuaj potassium permanganate (10 liv dej - 5 g) tsim cov xwm txheej zoo heev rau kev ntshai tsam kab tawm. Koj tuaj yeem siv infusions ntawm wormwood thiab tansy.
Kev daws ntawm mustard hmoov diluted hauv peb liv dej sov kuj tseem siv. Txoj kev lis ntshav ntawm cov ntoo tshauv yog suav tias yog kev kho zoo ib yam: 3 kg ntawm tshauv thiab xab npum ntxhua khaub ncaws (40 g) tau siv rau 10 liv dej. Cov hav txwv yeem tau txau nrog txoj kev lis ntshav no thaum lub paj tawg.
Cov kws paub dhau los tseem tau qhia kom sim cov tshuaj hauv qab no: hauv 10 liv dej, ua ntej dilute ammonia (2 diav), thiab tom qab ntawd iodine (1 teaspoon). Cov hav txwv yeem raug kho nrog thawj qhov kev daws teeb meem thaum pib caij nplooj ntoo hlav, sai li sai tau thaum cov nplooj tawm tuaj, thiab nrog qhov thib ob, ob lub lis piam tom qab.
Yog tias muaj 3 - 4 kab ntawm ib tsob ntoo, siv tshuaj tua kab: ntawm raspberries lawv tau siv nyob rau theem ntawm kev nthuav tawm cov paj, thiab ntawm txiv pos nphuab - thaum pib ntawm lawv rov tsim dua. Txau nrog corsair, actellik, vofatox, ambush, metaphos, gardona, thiab lwm yam yog ua tiav. Nws yuav tsum tau nqa tawm tsis pub dhau tsib hnub ua ntej pib ua paj ntoo. Kev ua cov raspberries ua ntej paj, ntxiv rau tom qab sau nrog fufanon lossis karbofos, kuj tseem pab tau.
Kev npaj tshuaj lom neeg tseem tau ua pov thawj lawv tus kheej zoo heev hauv kev tawm tsam raspberry weevil (fitoverm, acarin, spark -bio) - cov nroj tsuag yuav tsum tau kho nrog lawv thaum pib lub Tsib Hlis.
Ib txoj hauv kev ntawm kev sib ntaus cov cab no kuj tseem siv tau: cov yeeb yaj kiab lossis lwm yam khoom siv tau kis rau hauv av, uas cov kab liab liab tau tshee hnyo. Tom qab ntawd cov kab uas tau sau yuav tsum raug rhuav tshem. Cov txheej txheem tau ua tiav, raws li txoj cai, ua ntej thawj paj tuaj tawm, nrog rau thaum kawg ntawm kev sau cov txiv hmab txiv ntoo nyob rau hauv ib nrab ntawm lub Yim Hli (tiv thaiv cov kab mob me). Lub sijhawm sawv ntxov yuav zoo tagnrho rau nws qhov kev coj ua - kab mob kis thaum sawv ntxov yog qhov txawv ntawm qhov tsis ua haujlwm.
