Kuphatikiza pa halosulfuron-methyl, mankhwala otetezeka popewa ndi kuwongolera kwa cypeus plandus ndi Rimsulfuron

Chifukwa cha kuwonongeka kocheperako komanso kuwonongeka kwa Rimsulfuron m'nthaka ndi mbewu zotsatila ku Mlingo wolimbikitsidwa, womwe ndi kusiyana kwakukulu pakati pa chinthu ichi ndipoHalosulfuron-methyl.

Makamaka zogwiritsidwa ntchito poyang'anira chimanga, mbatata, konjac, fodya, tsabola wokoma, ndi mankhwala ena achi China.

Sizongoletsa ndi kuyendetsa Cyperus Crudulas, komanso a namsongole othandiza pachaka komanso otambalala a tirigu wa tirigu , Pursneona, kachikwama kaubusa, ndi bakha.

Ma naed omwe ali pamwambawa amawongolera bwino m'mayendedwe awo, koma zotsatira zake zimakhala zovuta m'malo awo akuluakulu ndipo amakonda kubwezeretsa.

Mphamvu ya Rimsulfuron ndikuti zosakaniza zoyendetsedwa ndi zimayambira, masamba, ndi mizu ya namsongole, ndikulepheretsa kugawanika kwa masente .

Zomwe zimapangitsa kuti ziwoneke mu ubongo wambiri mkati mwa masiku atatu, koma zimatenga nthawi yayitali kuti zifike udzu wakufa. Mwachitsanzo, nthawi zambiri zimatenga masiku opitilira 20 kuti aconite afe kwathunthu ndi poyizoni. Pamene chinyezi cha dothi ndi chochepa, nthawi yakufa iyenera kufalikira kwa masiku 30.

Kugwiritsa ntchito rimsulfuron mu mbewu zosiyanasiyana

① minda ya chimanga

Kugwiritsa ntchito rimsulfuron mu gawo la chimanga kuyenera kuchitidwa mu 3-5 gawo la masamba a chimanga, 2-4 gawo la masamba obiriwira ndi 3-4 gawo la masamba otambalala. Namsongole atakwanira, 5-7G ya 25% Rimsulfuron ayenera kugwiritsidwa ntchito ponse. Pambuyo pa kuchepetsedwa kwachiwiri (kofunikira), 30kg yamadzi iyenera kuwonjezeredwa kuti ipsupsa.

② Minda ya Chili

Mukamagwiritsa ntchito Rimsulfuron mu minda ya tsabola, ndipo iyenera kugwiritsidwa ntchito pambuyo pa gawo lapang'onopang'ono la mmera wa tsabola wa chililofop-p-ethyl kapena a clethodim mu gawo la namsongole. Zimatha kukonza mwayi wothetsa udzu wa udzu ndipo umakhala ndi mphamvu zambiri pa nanelo wamba yowoneka bwino mu minda yofanana ndi aconitum, Amaranus, ndi Pordusca.

Chidziwitso: Mukamagwiritsa ntchito rimsulfuron mu minda ya tsabola, kutsuka kowongolera kuyenera kutengedwa.

③ Minda ya mbatata

Pakulemba kwa mmera wa mbatata, utsi wowongolera pakati pa zitunda umafunikiranso. Gawo la masamba 2-5 la namsongole ndi nthawi yabwino kwambiri yolamulira. Pansi pa mtengo wolimbikitsidwa mu, tikulimbikitsidwa kusakaniza ndi Qualofop-p-ethyl kapena a clethodim. Kuchulukitsa kachulukidwe kumakhala kokwera, ogwiritsa ntchito amatha kuwonjezeredwa pamodzi.
