Kugwiritsa ntchito kwakukulu
Diformimide imagwira bwino kwambiri sipekitiramu, kukhudzana ndi fungicide. Imagwira ntchito pa spores, mycelia ndi sclerotium nthawi imodzi, ndikuletsa kumera kwa spore ndi mycelia kukula.h.Iprodione pafupifupi sungalowe muzomera ndipo ndi fungicide yoteteza. Ili ndi bactericidal effect pa Botrytis cinerea, Sclerotinia, Streptospora, sclerotinia ndi Cladosporium.
1. Yambani kupopera mbewu mankhwalawa phwetekere oyambirira choipitsa pafupifupi 10d pambuyo kupatsidwa zina phwetekere ndi 50% yonyowa ufa 11.3 ~ 22.5g/100m2, kupopera mbewu mankhwalawa kamodzi pa milungu 2, okwana 3 ~ 4 zina;
2. Kuwongolera imvi nkhungu matenda asanayambe mankhwala, ndi 50% yonyowa ufa 5g/100m2, iliyonse 10 ~ 14d kutsitsi kamodzi (maluwa, fruiting nthawi ndi bwino), okwana 3 ~ 4 nthawi, akhoza kusintha zokolola ndi khalidwe la tomato.
3. Kuthira mbeu ndi 100 ~ 200g yamankhwala oyambilira pa 100 kg ya njere kumatha kuwononga smut yoyambitsidwa ndi Verminium graminis ndi Megalomelus triticum.
4. Pogwiritsa ntchito 50% ufa wonyowa pokonzekera 4g/L ndende ya mankhwala kuti zilowerere mbewu ya mbatata ya mbatata, isomylurea imateteza ku nigrosis yoyambitsidwa ndi rhizoctonia.
5. Mankhwala a anyezi ndi babu adyo amatha kuteteza ndi kuchiza zowola zakuda. Ndi 50% wonyowa ufa 11.3 ~ 15g/100m2, utsi kamodzi pa chiyambi maluwa siteji ndi zonse maluwa siteji, zingalepheretse sclerotinia sclerotinia kugwiriridwa. Mankhwalawa ayenera kugwiritsidwa ntchito mosinthana kapena kusakaniza ndi othandizira ena kuti apewe kukana mankhwala.
Zindikirani:
1. Sizingasakanizidwe kapena kuzunguliridwa ndi fungicides omwe ali ndi machitidwe omwewo, monga prophyritic (Sukylin) ndi vinylidene (nunrilin).
2. Sizingasakanizidwe ndi mankhwala amchere amphamvu kapena acidic.
3. Pofuna kupewa kufalikira kwa mitundu yolimbana ndi matenda, nthawi yogwiritsira ntchito Iprodione pa nthawi yonse ya kukula kwa mbewu iyenera kuyendetsedwa mkati mwa nthawi za 3, ndipo zotsatira zabwino zingapezeke pamene matendawa akugwiritsidwa ntchito kumayambiriro komanso asanadye. nsonga.
Ntchito
Iprodionendi mankhwala opha tizilombo toyambitsa matenda, omwe amagwira ntchito pa spores ndi mycelia nthawi imodzi, ndipo ali ndi mphamvu pa Botrytis cinerea, Pedospora, Sclerotinia, ndi Alternaria. Isomylurea itha kugwiritsidwanso ntchito ngati chithandizo cha mbewu.
