Fludioxonil imatha kuletsa ndi kupha mabakiteriya.Njira ya bactericidal ndiyo kusokoneza ndikuwononga makutidwe ndi okosijeni achilengedwe komanso njira ya biosynthesis.

mabakiteriya, amawononga unyolo wa hydrophobic pa nembanemba ya cell ya mabakiteriya, ndikusungunula ndi kusungunula zinthu zazikulu zamoyo wa mabakiteriya.

Kusamutsa kwa glucose kokhudzana ndi phosphorylation kuti kumangirire kukula kwa mycelium.

Fludioxonil itha kugwiritsidwa ntchito ngati zokutira mbewu, kupopera mbewu mankhwalawa, ndi kuthirira mizu, ndipo imagwira ntchito motsutsana ndi choipitsa, zowola za mizu, nkhungu zotuwa, ndi mafangasi omwe amapezeka m'mbewu zosiyanasiyana.

Matenda a nyukiliya ndi Fusarium wilt ali ndi zotsatira zowongolera.

Kodi ntchito ndi kugwiritsa ntchito fludioxonil ndi chiyani?

1. Ntchito

(1) Fludioxonil ili ndi bactericidal ndi antibacterial zotsatira.Kwa Botrytis cinerea, makina ake ophera mabakiteriya ndikusokoneza ndikuwononga makutidwe ake achilengedwe.

ndi biosynthesis process (ndiko kuti, kusungunula khoma la cell la Botrytis cinerea) ndikuwononga mwachangu nembanemba ya cell ya Botrytis cinerea.

Amasungunula zinthu zazikulu za moyo wa mabakiteriya, ndikuwononga kaphatikizidwe ka nucleic acid ndi mapuloteni.

(2) Fludioxonil imalepheretsa kukula kwa fungal mycelium poletsa kusamutsa kokhudzana ndi glucose phosphorylation, ndipo pamapeto pake kumabweretsa kufa kwa tizilombo toyambitsa matenda.

Imfa.

2. Cholinga

(1) Fludioxonil alibe mtanda kukana ndi fungicides alipo, ndipo angagwiritsidwe ntchito ngati mbewu mankhwala fungicides ndi kuyimitsidwa ❖ kuyanika mbewu.Pochiza matenda

mbewu, zomwe zimagwira ntchito zimangotengedwa pang'ono, koma zimatha kupha majeremusi pamwamba pa njere ndi muchovala chambewu.

(2) Mukamagwiritsa ntchito fludioxonil kuthirira mizu kapena kuthirira dothi, imatha kupewa ndikuletsa zowola, fusarium wilt, blight, choipitsa ndi matenda ena.

pa mbewu zosiyanasiyana.Popopera mbewu mankhwalawa, zimatha kupewa sclerotinia, imvi nkhungu ndi matenda ena.

Momwe mungagwiritsire ntchito fludioxonil

1. Kupaka

Mukabzala chimanga, mbatata, tirigu, soya, adyo, nkhaka, mtedza, mavwende, mavwende ndi mbewu zina, muzigwiritsa ntchito musanafese.

2.5% fludioxonil kuyimitsidwa ❖ kuyatira mbewu kwa mbewu kuvala, chiŵerengero cha madzi ndi mbewu ndi 1:200-300.

2. Kuviika maluwa

(1) Mukabzala tsabola, biringanya, mavwende, tomato, zukini, sitiroberi, nkhaka, mavwende ndi mbewu zina, gwiritsani ntchito kuyimitsidwa kwa fludioxonil 2.5%

ganizirani nthawi 200 (10ml mankhwala wothira 2kg madzi) + 0,1% forchlorfenuron madzi Sunse maluwa ndi 100-200 nthawi wa wothandizira.

(2)Akaviika maluwawo, amatha kuteteza nkhungu zotuwira, kusunga masamba atsopano kwa nthawi yayitali, komanso kuletsa masamba monga biringanya ndi tomato kuti zisawole.

3. Utsi

Angagwiritsidwe ntchito kumayambiriro siteji ya matenda kupewa imvi nkhungu wa mphesa, strawberries, tsabola, biringanya, nkhaka, tomato, mavwende ndi mbewu zina.

2000-3000 nthawi zamadzimadzi a 30% pyridoyl·fludioxonil kuyimitsidwa maganizo ayenera sprayed kamodzi pa masiku 7-10.

4. Kuthirira mizu

Pofuna kupewa fusarium wilt ndi mizu yowola mu biringanya, mavwende, nkhaka, phwetekere, sitiroberi ndi mbewu zina, mizu imatha kuthiriridwa ndi 800-1500 nthawi za 2.5%.

Kuyimitsidwa kwa fludioxonil kumayambira kumayambiriro kwa matendawa, kamodzi pa masiku 10, ndi kuthirira kosalekeza 2-3.
