Izintwala zikakolweni

Izintwala zikakolweni zigcwala emaqabungeni, eziqwini nasezindlebeni ukuze zimunce ubisi. Amachashazi amancane aphuzi avela kulowo ohlukunyeziwe, bese eba imivimbo, futhi sonke isitshalo sibuna size sife.

Izinambuzane zikakolweni ziyabhoboza futhi zimunce ukolweni futhi zithinte i-photosynthesis kakolweni. Ngemva kokungena esiteji, ama-aphid agxila ezindlebeni zikakolweni, akhe okusanhlamvu okubolile futhi anciphise isivuno.

Izinyathelo zokulawula

Ukusebenzisa uketshezi lwe-Lambda-cyhalothrin25%EC izikhathi ezingu-2000 noma uketshezi lwe-Imidacloprid10% WP izikhathi ezingu-1000.

 

I-midge kakolweni

Izibungu zicathamela egobolondweni le-glume ukuze zimunce ujusi wezinhlamvu zikakolweni ezigaywayo, zibangele amakhoba namagobolondo angenalutho.

 

Izinyathelo zokulawula:

Isikhathi esingcono kakhulu sokulawula i-midge: ukusuka ekuhlanganiseni kuya esigabeni sokuqala. Ngesikhathi se-pupal ye-midges, ingalawulwa ngokufafaza inhlabathi yokwelapha. Ngesikhathi sesihloko kanye nesikhathi sokuqhakaza, kungcono ukhethe ama-insecticide asebenza isikhathi eside, njengeLambda-cyhalothrin + imidacloprid, futhi angakwazi ukulawula ama-aphid.

 

Isicabucabu sikakolweni (esaziwa nangokuthi isicabucabu esibomvu)

Amachashazi aphuzi namhlophe avela emaqabunga, izitshalo zifushane, zibuthakathaka, zishwabene, ngisho nezitshalo ziyafa.

 

Izinyathelo zokulawula:

Abamectin,imidacloprid,I-Pyridaben.

 

I-Dolerus tritici

I-Dolerus tritici ilimaza amaqabunga kakolweni ngokuluma. Amaqabunga kakolweni angadliwa aphele.I-Dolerus tritici ilimaza amaqabunga kuphela.

 

Izinyathelo zokulawula:

Imvamisa, i-Dolerus tritici ayibangeli umonakalo omkhulu kukolweni, ngakho-ke akudingekile ukufutha. Uma kunezinambuzane eziningi, udinga ukuzifutha. Izibulala-zinambuzane ezivamile zingawabulala.

Isibungu senaliti segolide sikakolweni

Izibungu zidla imbewu, amahlumela, nezimpande zikakolweni emhlabathini, okwenza izitshalo zibune futhi zife, noma zicekele phansi insimu yonke.

 

Izinyathelo zokulawula:

(1) Ukufakwa kwembewu noma ukuhlanzwa kwenhlabathi

Sebenzisa i-imidacloprid, i-thiamethoxam, ne-carbofuran ukuze welaphe imbewu, noma usebenzise i-thiamethoxam kanye nezinhlamvana ze-imidacloprid zokwelashwa kwenhlabathi.

(2) Ukwelashwa ngenkasa yezimpande noma ukufutha

Sebenzisa i-phoxim, i-lambda-cyhalothrin ngokunisela izimpande, noma fafaza ngqo ezimpandeni.
