Ⅰ. Imifino
U-April yinkathi yentwasahlobo, futhi futhi iyinkathi yokukhula kwezilimo eziningi. Kodwa-ke, intwasahlobo nayo iyinkathi yezinambuzane ezimbi kakhulu. Ngakho-ke, izitshalo eziningi zidinga ukusebenzisa izibulala-zinambuzane ukulawula izinambuzane. Isibonelo, imifino efana nekhukhamba, ikhabe, isitshalo seqanda, nopelepele isengozini ezinambuzaneni ezinjenge- borer, leafhoppers enamabala kanye nezimpukane ezimhlophe ngesikhathi sokukhula. Ukuvikela lezi zitshalo, izibulala-zinambuzane eziqukethe ukulawula lezi zinambuzane, njenge-cypermethrin, imidacloprid, njll.
Ngo-April, izifo zemifino kanye nezinambuzane okufanele kugxilwe kuzo zihlanganisa isikhunta esimpunga, i-downy mildew, ama-aphid, inundu ye-diamondback, nezinye izifo nezinambuzane ezihlanganisa i-sclerotia, i-leaf miner, ne-yellow stripe jump. Mayelana nokuvimbela nokulawula, kufanele sinake ukuvimbela izifo, futhi sihlole ngesikhathi esifanele futhi siphathe izinambuzane ezinambuzane ukuze kuqinisekiswe ukukhula okuvamile kwemifino ensimini entwasahlobo.
Ukuvela kwezifo eziyinhloko nezinambuzane kanye neziphakamiso zokulawula imithi.
(1) Isikhunta esimpunga: Lesi sifo siyisifo esiyinhloko kutamatisi wendawo futhi sizongena eqophelweni eliphezulu maphakathi no-April. Ngaphambi kokuqala kwekhukhamba, i-manganese zinc (M-45) ingasetshenziselwa ukuvimbela ikhukhamba, futhi esigabeni esilandelayo, i-graft (esheshayo), i-anisoclurea (buhein), i-pyrimethamycin, i-diacilamide, i-pyritocycloisocourea, namanye ama-ejenti angasetshenziswa. .
(2) Isifo se-Downy isikhutha: Lesi sifo siyisifo esivamile kuulethisi wasentwasahlobo wendawo, isipinashi, amakhabe. Amakhabe okuqala okutshala (ikhukhamba) azongena esikhathini sokukhula esiphezulu ngasekupheleni kuka-April. Ingakhetha ukhilimu, i-manganese zinc, i-frost urea, i-manganese zinc, i-zinc ye-frost manganese embi, i-enolymorpholine, i-frost mildew, namanye ama-ejenti.
(3) Izintwala zilimaza kakhulu ubhontshisi, i-cruciferous, isolanum, amakhabe, neminye imifino. Ngokulawulwa kwakamuva, ama-aphid angaphansi kokulawulwa ngempumelelo. Ingakhetha i-amidine, imidacloprid, amine, namanye ama-ejenti, futhi iphathe i-lacia tabaci yemifino yezithelo.
(4) Ibhu le-Diamondback: Ngokocwaningo, i-cauliflower emasimini angu-13 yayinesilinganiso sezitshalo eziyi-12.6 kuya kweziyi-100, ezinohlu lwamakhanda angu-0-100, ikakhulukazi izibungu ezincane ensimini. I-Abamectin, amavithamini, i-acitral, i-ethyl polybiocidin, i-thuringiensis, namanye ama-agent angakhethwa.
(5) Ezinye izifo nezinambuzane: Isifo se-Fusarium wilt singelashwa nge-Rotmilben, isobacterium urea, acinamide, i-methylsulfur bacterium agent. Abavukuzi bamaqabunga bangelashwa nge-avermectin, i-phoxim, namanye ama-ejenti. Ukwelashwa komhlabathi kwe-yellow stripe jump kungasetshenziswa ukulawula izibungu. Esigabeni sezithombo, ingasetshenziswa, esigabeni sokugcina sokukhula, i-fluoride ephezulu (i-arica), i-fluoride ephezulu (i-fuqi), i-benzamide, namanye ama-agent angasetshenziswa ukulawula. Endabeni yokuvela okuxubile kwezifo ezihlukahlukene kanye nezinambuzane zezinambuzane, ama-agent ahlosiwe angasetshenziswa ndawonye.
Izindaba Nokunakwa
Ukusetshenziswa okuqhubekayo kwe-ejenti efanayo; musa ukwandisa ukusetshenziswa kwezibulala-zinambuzane; yeka imithi ezinsukwini ezingu-7-10 ngaphambi kokuvuna ukuze ugweme izinsalela eziningi zezibulala-zinambuzane.
Isikhathi sokuthumela: Mar-30-2023
