Nsabwe za tirigu

Nsabwe za tirigu zimachuluka pamasamba, zimayambira, ndi m’makutu kuti ziziyamwa madzi. Mawanga achikasu ang'onoang'ono amawonekera pa wozunzidwayo, ndiyeno amakhala mikwingwirima, ndipo chomera chonsecho chimafota mpaka kufa.

Nsabwe za tirigu zimabaya ndi kuyamwa tirigu ndipo zimakhudza photosynthesis ya tirigu. Ikafika pachimake, nsabwe za m'masamba zimakhazikika m'makutu a tirigu, kupanga tirigu wowonongeka ndikuchepetsa zokolola.

Njira zowongolera

Kugwiritsa ntchito madzi a Lambda-cyhalothrin25%EC kapena 1000times madzi a Imidacloprid10%WP.

 

Mbalame ya tirigu

Mphutsizi zimabisala m’chigoba cha glume kuti ziziyamwa madzi ambewu zatirigu amene akuganyulidwa, kuchititsa mankhusu ndi zipolopolo zopanda kanthu.

 

Njira zowongolera:

Nthawi yabwino yowongolera midge: kuyambira pakuphatikizana mpaka poyambira. Pa nthawi ya pupal ya midges, imatha kuwongoleredwa ndi kupopera mbewu mankhwalawa dothi. Panthawi yamutu ndi maluwa, ndi bwino kusankha mankhwala ophera tizilombo okhala ndi nthawi yayitali, monga Lambda-cyhalothrin + imidacloprid, ndipo amathanso kuwongolera nsabwe za m'masamba.

 

Kangaude wa Tirigu (wotchedwanso kangaude wofiira)

Madontho achikasu ndi oyera amawonekera pamasamba, zomera zimakhala zazifupi, zofooka, zofota, ndipo ngakhale zomera zimafa.

 

Njira zowongolera:

Abamectin,imidacloprid,Pyridaben.

 

Dolerus tritici

Dolerus tritici amawononga masamba a tirigu poluma . Masamba a tirigu akhoza kudyedwa kwathunthu. Dolerus tritici imawononga masamba okha.

 

Njira zowongolera:

Nthawi zambiri, Dolerus tritici sawononga kwambiri tirigu, kotero sikoyenera kupopera mbewu mankhwalawa. Ngati pali tizilombo tambiri, muyenera kupopera mbewu mankhwalawa. Mankhwala ophera tizilombo amatha kuwapha.

Nyongolotsi ya singano yagolide ya tirigu

Mphutsi zimadya mbewu, mphukira, ndi mizu ya tirigu m’nthaka, zomwe zimachititsa kuti mbewuzo zifote ndi kufa, kapena kuwononga munda wonsewo.

 

Njira zowongolera:

(1) Kuthira mbewu kapena kuthira nthaka

Gwiritsani ntchito imidacloprid, thiamethoxam, ndi carbofuran pochiza mbewu, kapena gwiritsani ntchito thiamethoxam ndi imidacloprid granules pochiritsa nthaka.

(2) Chithandizo cha kuthirira mizu kapena kupopera mbewu mankhwalawa

Gwiritsani ntchito phoxim, lambda-cyhalothrin pothirira mizu, kapena kupoperani mizu mwachindunji.
