Izinambuzane eziqhelekileyo emasimini eentongomane zezi: amachaphaza amagqabi, ukubola kweengcambu, ukubola kwesiqu, ii-aphids, i-cotton bollworm, izinambuzane ezingaphantsi komhlaba, njl.
Isicwangciso sokukhuhla ukhula kwintsimi yamandongomane:
Ukukhuhla ukhula kwintsimi yamandongomane kukhuthaza ukunyangwa komhlaba emva kokutyala nangaphambi kokuba kuhlume izithole. Singakhetha i-0.8-1L 960 g/L Metolachlor EC ngehektare nganye,
okanye 2-2.5L 330 g/L Pendimethalin EC ngehektare njl.
Izibulali-zinambuzane ezingentla mazitshizwe ngokulinganayo emhlabeni emva kokuba amandongomane etyaliwe nangaphambi kokuba kuvele, kwaye amandongomane agqunywe ngefilimu emva nje kokusetyenziswa.
Kwimithi yesiqu namagqabi emva kokuhluma, i-300-375 ml ngehektare nganye ye-15% yeQuizalofop-ethyl EC, okanye i-300-450 ml ngehektare nganye ye-108 g/L iHaloxyfop-P-ethyl EC ingasetyenziswa kwinqanaba lamagqabi ama-3-5 okhula lwengca;
Ngexesha lesigaba samagqabi ama-2-4 engceni, i-300-450 ml kwihektare nganye ye-10% ye-Oxyfluorfen EC ingasetyenziselwa ukulawula ukutshiza kwiziqu zamanzi kunye namagqabi.
Isicwangciso solawulo esidibeneyo ngexesha lokukhula
1. Ixesha lokuhlwayela
Ixesha lokuhlwayela lixesha elibalulekileyo lokulawula ngempumelelo izinambuzane nezifo ezahlukeneyo. Ingxaki ephambili ikunyango lwembewu kunye nokuthintela, kubaluleke kakhulu ukukhetha izibulali-zinambuzane ezisebenzayo kakhulu, ezinobungozi obuphantsi, nezihlala ixesha elide ukulawula izifo zeengcambu kunye nezinambuzane ezingaphantsi komhlaba.
Singakhetha i-22% yeThiamethoxam+2% yeMetalaxyl-M+ 1% yeFludioxonil FS 500-700ml exutywa nembewu ye-100kg.
Okanye i-3% yeDifenoconazole+32% yeThiamethoxam+3% yeFludioxonil FS 300-400ml xa ixutywa nembewu ye-100kgs.
Kwiindawo apho izinambuzane ezingaphantsi komhlaba ziyingozi kakhulu, singakhetha i-0.2%
I-Clothianidin GR 7.5-12.5kg .Faka ngaphambi kokutyala amandongomane, uze uhlwayele emva kokurhawula umhlaba ngokulinganayo.
Okanye i-3% ye-Phoxim GR 6-8kg, ifakwa ngexesha lokuhlwayela.
Imbewu egayiweyo okanye egqunyiweyo kufuneka ityalwe emva kokuba igqunywe ngembewu, kungcono ukuba ityalwe zingadlulanga iiyure ezingama-24.
2. Ngexesha lokuhluma ukuya kwixesha lokuqhakaza
Ngeli xesha, izifo eziphambili ziindawo ezinamabala amagqabi, ukubola kweengcambu kunye nesifo sokubola kwesiqu. Singakhetha i-750-1000ml ngehektare ye-8% yeTebuconazole +22% yeCarbendazim SC, okanye i-500-750ml ngehektare ye-12.5% yeAzoxystrobin +20% yeDifenoconazole SC, sitshiza ngexesha lokuqala kwesifo.
Ngeli xesha, izinambuzane eziphambili yiAphis, iCotton bollworm kunye nezinambuzane ezingaphantsi komhlaba.
Ukulawula ii-aphids kunye ne-cotton bollworm, singakhetha i-300-375ml ngehektare nganye ye-2.5% ye-Deltamethrin EC, ukutshiza ngexesha lesigaba sokuqala se-Aphis kunye nesigaba sesithathu sokuqala se-cotton bollworm.
Ukulawula izinambuzane ezingaphantsi komhlaba, singakhetha i-1-1.5kg ye-15%Chlorpyrifos GR okanye i-1.5-2kg ye-1% Amamectin +2% Imidacloprid GR, esasaza.
3. Ixesha le-pod ukuya kwixesha lokuvuthwa ngokupheleleyo kwesiqhamo
Kucetyiswa ukuba kusetyenziswe amayeza axutyiweyo (i-insecticide + fungicide + plant growth regulator) ngexesha lokubekwa kwe-peanut pod, nto leyo enokulawula ngempumelelo izifo ezahlukeneyo kunye nezinambuzane kwisigaba esiphakathi nesokugqibela, ikhusele ukukhula okuqhelekileyo kwamagqabi e-peanut, ithintele ukuguga kwangaphambi kwexesha, kwaye iphucule ukuvuthwa.
Ngeli xesha, izifo eziphambili ngamachaphaza amagqabi, ukubola kwesiqu, isifo somhlwa, izinambuzane eziphambili yi-cotton bollworm kunye ne-aphis.
Singakhetha i-300-375ml ngehektare nganye ye-2.5% yeDeltamethrin + 600-700ml ngehektare nganye ye-18% yeTebucanozole + 9% yeThifluzamide SC+ 150-180ml ye-0.01% yeBrassinolide SL, yokutshiza.
