Ukusetshenziswa kwe-Iprodione

Ukusetshenziswa okuyinhloko

I-Diformimide esebenza kahle nge-broad-spectrum, uhlobo lokubulala isikhunta. Isebenza kuma-spores, i-mycelia kanye ne-sclerotium ngasikhathi sinye, ivimbela ukuhluma kwama-spores kanye nokukhula kwama-mycelia.h.Iprodione cishe ayingenwa ezitshalweni futhi iyisibulala-magciwane esivikelayo. Inethonya elihle lokubulala amagciwane ku-Botrytis cinerea, Sclerotinia, Streptospora, sclerotinia kanye ne-Cladosporium.

1. Qala ukufutha utamatisi ekuqaleni kokubola cishe izinsuku eziyi-10 ngemuva kokufakelwa utamatisi nge-50% yempuphu emanzi engu-11.3 ~ 22.5g/100m2, ufafaze kanye njalo emavikini ama-2, inani eliphelele izikhathi ezi-3 ~ 4;

2. Ukulawulwa kwesifo sesikhunta esimpunga ngaphambi kokuqala komuthi, nge-50% yempuphu emanzi engu-5g/100m2, njalo ngemva kwezinsuku eziyi-10 ~ 14 (isikhathi sokuqhakaza, isikhathi sokuthela izithelo singcono), inani eliphelele izikhathi ezi-3 ~ 4, lingathuthukisa isivuno kanye nekhwalithi katamatisi.

3. Ukwelashwa ngembewu ngomuthi wokuqala ongu-100 ~ 200g nge-100 kg yembewu kunomthelela wokulawula ukubola okubangelwa yi-Verminium graminis kanye ne-Megalomelus triticum.

4. Ukusebenzisa i-50% yempuphu emanzi ukulungisa ukuhlushwa okungu-4g/L kwesisombululo sokwelapha sokucwilisa amazambane embewu yamazambane, i-isomylurea inomphumela wokuvimbela i-nigrosis ebangelwa yi-rhizoctonia.

5. Ukwelashwa ngebhalbhu ka-anyanisi negalikhi kungavimbela futhi kwelaphe ukubola kokubola okumnyama. Nge-50% yempuphu emanzi engu-11.3 ~ 15g/100m2, fafaza kanye ngakunye esigabeni sokuqala sokuqhakaza kanye nesigaba sokuqhakaza esigcwele, kungavimbela i-sclerotinia sclerotinia ye-rape. Lesi sidakamizwa kufanele sisetshenziswe ngokushintshana noma sixutshwe nezinye izidakamizwa ukuze kugwenywe ukumelana nemithi.

Qaphela:

1. Ayikwazi ukuhlanganiswa noma ukujikeleziswa ngemithi yokubulala isikhunta enendlela efanayo yokusebenza, njengemithi yokuvimbela (i-Sukylin) kanye ne-vinylidene (nunrilin).

2. Ayikwazi ukuhlanganiswa nezinto ezinamandla ze-alkaline noma ze-acidic.

3. Ukuze kuvinjelwe ukuvela kwezinhlobo ezimelana nezifo, izikhathi zokusetshenziswa kwe-Iprodione esikhathini sonke sokukhula kwezitshalo kufanele zilawulwe zingakapheli izikhathi ezi-3, futhi imiphumela emihle kakhulu ingatholakala uma lesi sifo sisetshenziswa ekuqaleni nangaphambi kokufika kwe-peak.

Umsebenzi

Iprodioneiyi-contact fungicide, esebenza kuma-spores kanye ne-mycelia ngesikhathi esisodwa, futhi inomphumela wokulawula ku-Botrytis cinerea, Pedospora, Sclerotinia, kanye ne-Alternaria. I-Isomylurea ingasetshenziswa futhi njengokwelashwa kwembewu.
