Choletsedwa mwamphamvu Gwiritsirani ntchito mankhwalawa panthawi yamaluwa ndi njuchi, chifukwa iwo amaimira kalasi yoyamba ya poizoni.
Kodi mungakonzekere bwanji yankho?
Mu sprayer kutsanulira ¾ Kuchokera pamtunda wa thanki lonse la madzi oyera.
Malinga ndi malangizo, yanizani kuchuluka kwa mankhwalawa ndipo pang'onopang'ono muwatsanulire mu madzi.
Sakanizani osakaniza bwino. Kenaka yikani madzi mpaka tangi yadzazidwa kwathunthu mkati mwa mphindi 15 kuyambitsa yankho.
Pa hafu imodzi ya dera lanu muyenera kugwiritsa ntchito malita 200 a yankho.
Njira yogwiritsira ntchito
Mankhwalawa amagwiritsidwa ntchito pa kukula ndi chitukuko cha zomera pa nthawi ya maonekedwe a tizirombo. Mbewu, tirigu ndi mitengo ya zipatso zimayikidwa mosamala kumbali zonse, zomwe zimapereka chitetezo chodzala chomera.
Toxicity
Koma njuchi, kwa iwo, chida ichi chili ndi kalasi yoyamba ya poizoni ndipo chimayambitsa imfa.
