Kodi pali ubwino uliwonse wopopera mankhwala a herbicide kaye kenako nkupukutira, kapena kupopera mankhwala a herbicide kaye?" kenako nkupukutira? - adatero.
Kuzungulira kumeneku kumakankhira miyala pansi ndi kutali ndi chokolola, koma izi zimapangitsanso kuti nthaka ikhute, ngati "ngozi ya matayala," adatero Yackley.
“Pamene pali kupsinjika pang'ono, timakhala ndi kupsinjika kwambiri kwa udzu,” iye akufotokoza. “Chifukwa chake kugwedezeka kwa mawilo kumawoneka motere. Chifukwa chake tinkafunadi kuwona momwe kugwedezeka kwa udzu kumakhudzira udzu m'munda, kenako nkuyang'ananso momwe kugwedezeka kumakhudzirana ndi kugwiritsa ntchito mankhwala ophera udzu otsala.”
Eakley ndi gulu lake adachita mayeso oyamba a "kungosangalala" pa soya, koma akunena kuti mfundo za nkhaniyi ndi zomwe adapeza pambuyo pake mu mayeso a nyemba zodyedwa.
"Kumene tilibe mankhwala opukutira kapena mankhwala ophera udzu, tili ndi udzu pafupifupi 100 ndi mitengo 50 yovunda pa sikweya imodzi," adatero ponena za kuyesa koyamba mu 2022. "Kumene tinagubuduza, tinali ndi udzu wowirikiza kawiri ndipo tinali ndi udzu wochuluka katatu kuposa udzu wokulirapo."

Iye akupitiriza kufotokoza kuti kupukuta ndi kugwiritsa ntchito mankhwala otsala a herbicide nthawi imodzi kumatanthauza kuti udzu wambiri umatuluka koma umatetezedwa.
“Zimenezi zikutanthauza kuti tingathe kupha udzu wambiri mwanjira imeneyi,” iye anatero. “Chifukwa chake chimodzi mwa zomwe ndikuphunzira ndichakuti, ngati tikufuna kuyamba, onetsetsani kuti tili ndi ndalama zotsalira, zomwe zingatipindulitse mtsogolo.”
“Sitikuona kwenikweni zotsatirapo zambiri za udzu pambuyo pa kutuluka kwa zomera mkati mwa mbewu yokha,” iye anatero. “Chifukwa chake zikuwoneka bwino kwa ifenso.”
