Kugwiritsa ntchito Iprodione

Ntchito yaikulu

Diformimide ndi mankhwala ophera tizilombo toyambitsa matenda omwe amagwira ntchito bwino kwambiri, omwe ndi ofanana ndi a tizilombo toyambitsa matenda. Amathandiza pa spores, mycelia ndi sclerotium nthawi imodzi, kuletsa kumera kwa spores ndi kukula kwa mycelia.h.Iprodione Ndi yosalowa m'nthaka ndipo ndi mankhwala oteteza ku matenda a fungus. Imakhala ndi mphamvu yabwino yopha mabakiteriya pa Botrytis cinerea, Sclerotinia, Streptospora, sclerotinia ndi Cladosporium.

1. Yambani kupopera phwetekere msanga patatha masiku 10 mutabzala phwetekere ndi ufa wonyowa wa 50% 11.3 ~ 22.5g/100m2, kupopera kamodzi pa masabata awiri aliwonse, nthawi zonse katatu mpaka kanayi;

2. Kulamulira matenda a imvi musanayambe kugwiritsa ntchito mankhwalawa, pogwiritsa ntchito ufa wonyowa wa 50% 5g/100m2, nthawi iliyonse yothira 10 ~ 14d (nthawi yophukira maluwa ndi yabwino), nthawi zonse 3 ~ 4, kungathandize kukulitsa zokolola ndi ubwino wa phwetekere.

3. Kuchiza mbewu ndi 100 ~ 200g ya mankhwala oyamba pa 100 kg ya mbewu kumakhudza kwambiri smut yomwe imayambitsidwa ndi Verminium graminis ndi Megalomelus triticum.

4. Pogwiritsa ntchito ufa wonyowa wa 50% pokonzekera kuchuluka kwa 4g/L kwa mankhwala oyeretsera mbatata za mbewu, isomylurea imateteza ku nigrosis yomwe imayambitsidwa ndi rhizoctonia.

5. Chithandizo cha babu la anyezi ndi adyo chingateteze ndikuchiza kuwola kwa black bolt. Ndi ufa wonyowa wa 50% 11.3 ~ 15g/100m2, thirani kamodzi pa siteji yoyamba ya maluwa ndi siteji yonse ya maluwa, mutha kupewa sclerotinia sclerotinia ya rape. Chothandizira ichi chiyenera kugwiritsidwa ntchito mosinthana kapena kusakanikirana ndi zinthu zina kuti mupewe kukana mankhwala.

Zindikirani:

1. Sizingasakanizidwe kapena kuzunguliridwa ndi mankhwala ophera fungicide omwe ali ndi njira yofanana yogwirira ntchito, monga prophyritic (Sukylin) ndi vinylidene (nunrilin).

2. Sizingasakanizidwe ndi mankhwala amphamvu a alkaline kapena acidic.

3. Pofuna kupewa kubuka kwa mitundu yolimbana ndi matendawa, nthawi yogwiritsira ntchito Iprodione nthawi yonse yokulira ya mbewu iyenera kulamulidwa mkati mwa nthawi zitatu, ndipo zotsatira zabwino zitha kupezeka matendawa akagwiritsidwa ntchito pachiyambi komanso asanafike pachimake.

Ntchito

Iprodionendi mankhwala ophera tizilombo toyambitsa matenda omwe amagwira ntchito pa spores ndi mycelia nthawi imodzi, ndipo amawongolera Botrytis cinerea, Pedospora, Sclerotinia, ndi Alternaria. Isomylurea ingagwiritsidwenso ntchito ngati mankhwala ophera mbewu.
