I-Fludioxonil inokuthintela kwaye ibulale iibhaktheriya.Indlela ye-bactericidal kukuphazamisa kunye nokutshabalalisa inkqubo ye-biological oxidation kunye ne-biosynthesis ye-biosynthesis.

iibhaktheriya, zitshabalalisa ikhonkco le-hydrophobic kwi-membrane yeseli yebhaktheriya, kwaye i-oxidize kwaye inyibilikise izinto eziphambili zemisebenzi yobomi yebhaktheriya.

Ukudluliselwa kweglucose enxulumene ne-phosphorylation ukubamba ukukhula kwe-fungal mycelium.

I-Fludioxonil inokusetyenziselwa ukugquma kwembewu, ukutshiza, kunye nokunkcenkceshela kweengcambu, kwaye iyasebenza ngokuchasene nentsholongwane, ukubola kweengcambu, ukungunda okungwevu, kunye nokungunda okwenzeka kwizityalo ezahlukeneyo.

Isifo seNyukliya kunye neFusarium wilt zineziphumo zolawulo.

Yintoni umsebenzi kunye nokusetyenziswa kwe-fludioxonil

1. Umsebenzi

(1) I-Fludioxonil ineempembelelo ze-bactericidal kunye ne-antibacterial.Kwi-Botrytis cinerea, indlela yayo yokubulala iintsholongwane kukuphazamisa nokutshabalalisa i-oxidation yayo yebhayoloji.

kunye nenkqubo ye-biosynthesis (oko kukuthi, ukunyibilikisa udonga lweseli ye-Botrytis cinerea) kwaye utshabalalise ngokukhawuleza i-membrane yeseli ye-Botrytis cinerea I-oxidizes kwaye

Inyibilikisa izinto eziphambili zemisebenzi yobomi yebhaktheriya, kwaye itshabalalisa ukuhlanganiswa kwe-nucleic acid kunye neprotheni.

(2) I-Fludioxonil inqanda ukukhula kwe-mycelium yefungal ngokuvimbela ukuhanjiswa okuhambelana ne-glucose phosphorylation, kwaye ekugqibeleni ikhokelela ekufeni kwe-pathogen.

Ukufa.

2. Injongo

(1) I-Fludioxonil ayinayo ukumelana nemichiza yokungunda esele ikho, kwaye ingasetyenziswa njengonyango lwembewu yokubulala umngundo kunye nee-arhente zokuxhoma zokugquma kwembewu.Xa unyango lwe

imbewu, isithako esisebenzayo siya kuxutywa kuphela kwisixa esincinci, kodwa sinokubulala iintsholongwane kumphezulu wembewu kunye nengubo yembewu.

(2) Xa usebenzisa i-fludioxonil ukunkcenkceshela iingcambu okanye ukunyanga umhlaba, inokuthintela kwaye ilawule ukubola kweengcambu, i-fusarium wilt, blight, blight kunye nezinye izifo.

kwizityalo ezahlukeneyo.Xa utshiza, unokuthintela i-sclerotinia, i-gray mold kunye nezinye izifo.

Uyisebenzisa njani i-fludioxonil

1. Ukwaleka

Xa utyala umbona, iitapile, ingqolowa, iimbotyi zesoya, ikonofile, ikomkomkomere, amandongomane, ivatala, ivatala nezinye izityalo, zisebenzise ngaphambi kokuhlwayela.

I-2.5% ye-fludioxonil yokuxhoma i-ejenti yokwaleka kwembewu yokunxitywa kwembewu, umlinganiselo wolwelo kwimbewu yi-1:200-300.

2. Ukudipha iintyatyambo

(1) Xa utyala iipepile, ii-eggplants, ivatala, iitumato, izucchini, amaqunube, iikomkomere, ivatala kunye nezinye izityalo, sebenzisa i-2.5% fludioxonil suspension

concentrate 200 amaxesha (10ml ichiza exutywe 2kg amanzi) + 0.1% forchlorfenuron amanzi Dipha iintyatyambo kunye 100-200 amaxesha arhente.

(2)Emva kokudipha iintyatyambo, kunokuthintela ukungunda okungwevu, ukugcina amagqabi amatsha ixesha elide, kwaye kuthintele imifuno enjengeeggplants kunye neetumato ekuboleni.

3. Tshiza

Ingasetyenziswa kwisigaba sokuqala sesi sifo ukukhusela ukungunda okungwevu kweediliya, amaqunube, iipepile, ii-eggplants, iikomkomere, iitumato, iivatala kunye nezinye izityalo.

2000-3000 amaxesha ulwelo 30% pyridoyl·I-fludioxonil suspension concentrate kufuneka itshizwe kanye ngeentsuku ezi-7-10.

4. Ukunkcenkceshela ngeengcambu

Ukuthintela i-fusarium wilt kunye nokubola kweengcambu kwi-eggplant, i-watermelon, i-cucumber, i-tomato, i-strawberry kunye nezinye izityalo, iingcambu zinokunkcenkceshelwa ngamaxesha angama-800-1500 we-2.5%

Ukumiswa kwe-fludioxonil kugxininise kwinqanaba lokuqala lesi sifo, kanye ngeentsuku ezili-10, kunye nokunkcenkceshela okuqhubekayo ngamaxesha angama-2-3.
