Umbona sesinye sezona zityalo zixhaphakileyo. Bonke abalimi banethemba lokuba umbona abawutyalayo uya kuba nesivuno esikhulu, kodwa izinambuzane nezifo ziya kunciphisa isivuno sombona. Ngoko ke umbona ungakhuseleka njani kwizinambuzane? Ngowuphi amayeza afanelekileyo onokuwasebenzisa?
Ukuba ufuna ukwazi ukuba yeyiphi iyeza omawuyisebenzise ukuthintela izinambuzane, kufuneka uqale uqonde ukuba zeziphi izinambuzane ezikhula embona! Izinambuzane eziqhelekileyo embona ziquka iincukuthu, iimole crickets, i-cotton bollworm, iispider mites, ii-two-pointed noctuid moth, ii-thrips, ii-aphids, ii-noctuid moth, njl.njl.
1. Ngawaphi amayeza asetyenziswa ukulawula izinambuzane zombona
1. I-Spodoptera frugiperda ingalawulwa ngokubanzi ngeekhemikhali ezifana ne-chlorantraniliprole, i-emamectin, kunye neendlela ezifana nokutshiza, ukubamba ityhefu, kunye nokutyhefa umhlaba.
2. Ekulawuleni i-cotton bollworm, amalungiselelo e-Bacillus thuringiensis, i-emamectin, i-chlorantraniliprole kunye nezinye iikhemikhali zingasetyenziswa ngexesha lokuqandusela kwamaqanda.
3. Izinambuzane zesigcawu zinokulawulwa nge-abamectin, kwaye izinambuzane ezingaphantsi komhlaba kunye ne-thrips zinokulawulwa nge-cyantraniliprole njengonyango lwembewu.
4. Kucetyiswa ukuba kusetyenziswe i-dressing yembewu, i-oxazine kunye nezinye ii-dressing zembewu ukuthintela nokulawula ii-cutworms. Ukuba kwenzeka umonakalo phantsi komhlaba kwisigaba sokugqibela,i-chlorpyrifos, i-phoxim, kunyei-beta-cypermethriningasetyenziselwa ukunkcenkceshela iingcambu. Ukuba umonakalo mkhulu, ungatshiza i-beta-cypermethrin kufutshane neengcambu zombona ngokuhlwa, kwaye ikwanefuthe elithile!
5. Ukuthintela ii-thrips, kucetyiswa ukusebenzisa i-acetamiprid, i-nitenpyram, i-dinotefuran kunye nezinye iindlela zokulawula!
6. Ukulawula ii-corn aphids, kucetyiswa ukuba abalimi basebenzise i-70% ye-imidacloprid izihlandlo ezili-1500, i-70% ye-thiamethoxam izihlandlo ezingama-750, i-20% ye-acetamiprid izihlandlo ezili-1500, njl. Isiphumo silungile kakhulu, kwaye ukumelana kwee-corn aphids akukubi kangako!
7. Ukuthintela nokulawula iinundu ezidla ngokukhula: Ukuze kuthintelwe kwaye kulawulwe esi sinambuzane, kucetyiswa ukuba kusetyenziswe ezi zithako, ezifana ne-emamectin,i-indoxacarb, i-lufenuron, i-chlorfenapyr, i-tetrachlorfenamide, i-beta-cypermethrin, i-cotton boll polyhedrosis virus, njl.njl. ! Kungcono ukusebenzisa indibaniselwano yezi zithako ukuze ufumane iziphumo ezingcono!
