Pinoxaden: Imbere mu kwica ibyatsi mu murima w'ibinyampeke

Izina rusange ry'icyongereza ni Pinoxaden; izina ry'ikinyabutabire ni 8-(2,6-diethyl-4-methylphenyl)-1,2,4,5-tetrahydro-7-oxo-7H- Pyrazolo[1,2-d][1,4,5]oxadiazepine-9-yl 2,2-dimethylpropionate; Formula ya molekile: C23H32N2O4; Uburemere bwa molekile: 400.5; Nomero yo kwinjira ya CAS: [243973-20-8]; formula y'imiterere igaragara ku Ishusho. Ni umuti w'ibyatsi nyuma yo kuvuka kandi utoranijwe wakozwe na Syngenta. Watangijwe mu 2006 kandi kugurisha kwawo mu 2007 kwarenze miliyoni 100 z'amadolari y'Amerika.

Uburyo bw'ibikorwa

Pinoxaden iri mu bwoko bushya bw'imiti yica udukoko ya phenylpyrazoline kandi ni umuti ubuza acetyl-CoA carboxylase (ACC). Uburyo ikora ahanini ni ukubuza ikorwa rya aside irike, ibyo bigatuma ingirabuzimafatizo zifungana kandi zigapfa, ndetse n'urupfu rw'ibimera by'ibyatsi, bigatuma habaho imikorere myiza. Uyu muti ukoreshwa cyane cyane nk'umuti wica udukoko nyuma yo kumera mu mirima y'ibinyampeke mu kurwanya ibyatsi bibi.

Porogaramu

Pinoxaden ni umuti w’ibyatsi utoranya, uyobora ibyatsi mu buryo bw’umwimerere, ukora neza cyane, ufite imiterere yagutse, kandi winjira vuba mu biti no mu mababi. Nyuma yo kumera, ibyatsi bibi by’ingano n’ingano birwanya uburozi mu mirima y’ingano na sayiri, nka sagebrush, sagebrush y’Abayapani, ingano zo mu gasozi, ryegrass, thorngrass, foxtail, hard grass, serratia na thorngrass, nibindi. Ifite kandi ingaruka nziza zo kurwanya ibyatsi bibi by’ibyatsi nk’ibyatsi. Igipimo cy’ikintu gikora ni 30-60 g/hm2. Pinoxaden ikwiriye cyane ibinyampeke byo mu mpeshyi; kugira ngo hongerwe umutekano w’ibicuruzwa, hongerwaho fenoxafen irinda uburozi.

1. Gutangira vuba. Nyuma y'icyumweru kimwe kugeza kuri bitatu nyuma yo gufata umuti, ibimenyetso by'uburozi bw'ibimera bigaragara, maze meristem igahagarika gukura vuba kandi ikanakura vuba;

2. Umutekano mwinshi ku bidukikije. Umutekano ku bihingwa by’ingano, sayiri n’ibikomoka ku binyabuzima bitari ibyagenewe, umutekano ku bihingwa bizakurikiraho n’ibidukikije;

3. Uburyo ikora ni bwihariye kandi ibyago byo kudakora neza ni bike. Pinoxaden ifite imiterere mishya y’ibinyabutabire ifite ahantu hatandukanye ho gukora, ibyo byongera umwanya wayo mu bijyanye no gucunga uburyo bwo kudakora neza.
