Indlela yokwenza izibulali-zinambuzane zibe ngcono ngexesha lemvula?

A,Khetha elona xesha lifanelekileyo lokusebenzisa

Unokukhetha ukusebenzisa ixesha ngokwemikhwa yomsebenzi yezinambuzane, ezifana nezinambuzane zenundu ezifana ne-leaf rolls zisebenza ebusuku, ukukhusela kunye nokunyanga ezo zinambuzane kufuneka zisetyenziswe ngokuhlwa.

B,Khetha uhlobo oluchanekileyo lwezitshabalalisi

Ngexesha lemvula, ukukhusela, ukufunxa kwangaphakathi, isantya-esebenzayo, kunye ne-resistant -i-agent yokuxubha kufuneka ikhethwe.

1,Izitshabalalisi ezikhuselayo

Ngaphambi kosulelo lwe-pathogen, fafaza kumphezulu wesityalo ukuze udlale umphumo wokukhusela. NjengeCarbendazim, Thiram, Triadimefon.Captan, Etc

2,Ngokukhawuleza-isibulali zinambuzane

Izitshabalalisi ezisebenza ngokukhawuleza zinefuthe elinamandla kunye nefuthe lokutshisa. Inokubulala izinambuzane malunga neeyure ze-2 emva kokulawulwa, okunokuthi kuphephe ngokufanelekileyo ukunciphisa ukusebenza ngenxa yokuhlamba kwamanzi emvula. Njenge Deltamethrin, Malathion, Dimethoate njl.

3, Ukufunxa ngaphakathiisibulali-zinambuzane

Izibulali-zinambuzane zangaphakathi zinokungena emzimbeni wesityalo ngeengcambu, iziqu, amagqabi kunye nezinye iindawo zezityalo kwaye zithuthelwe kwezinye iindawo. Emva kweeyure ezi-5 zokufakwa, izitshabalalisi ezinjalo zinokufunxwa zizityalo malunga ne-80% yezithako ezisebenzayo. Iza kusebenza ngexesha, kwaye incinci kakhulu ngenxa yemvula.

Njenge Thiophanate methyl , Difenoconazole , Propiconazole , Metalaxyl .etc.

4,Isibulali-zinambuzane esimelana nemvula

Iiyure ezi-2-3 emva kwesicelo, nokuba idibana ne-rian enzima, ayichaphazeli umphumo we-pesticide, njenge-Chlorpyrifos, i-chlorothalonil, i-Azoxystrobin
