Fungicides

Fungicides rudzi rwemushonga wezvipembenene unoshandiswa kudzora zvirwere zvezvirimwa zvinokonzerwa nemhando dzakasiyana siyana dzepathogenic microorganisms.Fungicides yakakamurwa kuita inorganic fungicides uye organic fungicides zvichienderana nekuumbwa kwavo kwemakemikari.Kune marudzi matatu emishonga yefungicides: sulfur fungicides, copper fungicides, uye mercury fungicides;Organic fungicides inogona kukamurwa kuita organic sulfur (se mancozeb), trichloromethyl sulfide (se captan), substituted benzene (seChlorothalonil), pyrrole (seseed dressing), organic phosphorus (sealuminum ethophosphate), Benzimidazole (yakadaro. seCarbendazim), triazole (senge triadimefon, triadimenol), phenylamide (senge metalaxyl), nezvimwe.

Zvinoenderana nekudzivirira uye kurapa zvinhu, Inogona kukamurwa kuita Fungicide, bactericides, hutachiona hwekuuraya, etc. Zvinoenderana neModhi yechiito, inogona kukamurwa kuita inodzivirira fungicides, inhalable fungicides, etc. Zvinoenderana nekwakabva zvigadzirwa, inogona kupatsanurwa kuita makemikari ekugadzira fungicides, mishonga yekurima (yakadai sejinggangmycin, yekurima mishonga inorwisa mabhakitiriya 120), mishonga inouraya fungicides, chirimwa cheDefensin, nezvimwewo. Zvinoenderana nemafambisirwo ekuuraya zvipembenene, inogona kupatsanurwa kuita mapoka maviri: oxidizing uye non oxidizing. fungicides.Somuenzaniso, chlorine, Sodium hypochlorite, bromine, ozone uye chloramine ndiwo oxidizing bactericides;Quaternary ammonium cation, dithiocyanomethane, nezvimwewo haisi oxidizing fungicides.

1. Kuchenjerera kwekushandisa fungicidesPakusarudza fungicides, zvakakosha kunzwisisa maitiro avo.Kune marudzi maviri efungicides, imwe inodzivirira, iyo inoshandiswa kudzivirira zvirwere zvezvirimwa, zvakadai seBordeaux musanganiswa mvura, mancozeb, Carbendazim, nezvimwewo;Imwe mhando ndiyo mishonga yekurapa, iyo inoshandiswa mushure mekutanga kwechirwere chezvirimwa kuuraya kana kuvharidzira pathogenic mabhakitiriya anopinda mumuviri wechirimwa.Mishonga yekurapa ine mhedzisiro yakanaka mumatanho ekutanga echirwere, senge macompound fungicides akadai seKangkuning neBaozhida.

2. Mishonga yefungidziro inofanira kumwaiwa nguva dzepfumbamwe mangwanani kana kuti 4pm dzisati dzapera kuitira kudzivirira kushandiswa nezuva rinopisa.Kana ikapfapfaidzwa nezuva rinopisa, mushonga wezvipembenene unowanzoora uye kubuda mumhepo, izvo zvisingakodzeri kutora zvirimwa.

3. Mishonga yefungidziro haigoni kusanganiswa nemishonga ine alkaline.Usawedzera kana kuderedza huwandu hwefungicides inoshandiswa, uye shandisa sezvinodiwa.

4. Mishonga yefungidziri inowanzova hupfu, emulsion, uye suspensions, uye inofanira kuderedzwa isati yashandiswa.Paunenge uchinyungudutsa, tanga wawedzera mushonga, wozowedzera mvura, wozovhenganisa netsvimbo.Kana wasanganiswa nemimwe mishonga yezvipembenene, mushonga unofanirwa kutanga wadirwawo wozosanganiswa nemimwe mishonga.

5. Nguva yepakati pekushandisa fungicides mazuva 7-10.Kune vamiririri vane hutete hwekunamatira uye kutadza kunyura mukati, vanofanirwa kumwaya zvakare kana kunaya mukati maawa matatu mushure mekupfapfaidza.
