Pachysandra Leaf Blight on põhjustatud seenest, mis tekitab teie Pachysandra lehtedele pruunid laigud ja lõpuks muutuvad need laigud suurteks, ümbritsesid kogu lehte, kuni leht langeb. Selle seene taimede vabanemiseks ja edasiste nakkuste vältimiseks on olemas keemilised ja looduslikud viisid. Tsükli tundmine

Spordid, mis on väljaõppinud silmad, on tavaliselt kevadel märgatavad ja on roosad värvid. Need ilmuvad praegu nakatunud kudedele. Nad ei asu lehtedel lihtsalt. Nad nakatavad ka Pachysandra varred. Kui soe ilm jätkub suveks ja sügiseks, kogunevad eosed suurtes kogustes, mis on oranži värviga. Neid saab hõlpsasti täheldada ümber pruuni laiguga piirkonna. Seennakkuste peamine probleem on see, et paljud tõkendajad põhjustavad infektsiooni levikut.

Luuajate teadmine

Ennekõike on teie taime ebaõige hoolitsus osutunud peamiseks faktoriks enamiku taimede nakatumises. Kui teie taim on nõrgenenud või stressis, muutub ta vastuvõtlikumateks bakteriaalsete ja seenhaiguste ning ka kahjurite nakkuste tekkeks. Kahjurite teemal aitavad need väikesed poisid ka haigusi levida. Nad ei saa mitte ainult oma kehadesse sattuda eosidesse, kui nad oma taimedest kõnnivad, vaid nad kahjustavad lehti, luues haava, mida on lihtne nakatada seenorganismide spooridega. Eosed levivad nii kahjurite kui ka vihma, isegi tuulega. Seene armastab niiskeid tingimusi, et selliseid tingimusi juhtida ja teada, mis aitab katastroofi ära hoida.

Juhtimine

Väike taimede hügieen võib teie taime tervislikus seisundis oluliselt erineda. Taime väetamise ja korraliku jootmise abil muudate selle tugevaks ja tervislikuks, luues oma kaitsemeetmed kiskjate vastu. Põud ja ülemäärane päikesevalgus võivad lehti kahjustada, põhjustades infektsiooni tekkimist. Kui märkate oma tehases mingeid putukaid, veenduge, et need oleksid õigeaegselt kõrvaldatud. Kui tegemist on tõsise nakkusega, võib insektitsiid aidata, kuigi hea taimehügieen peaks seda kõige enam kaitsma.

Kui teie taimed on tihedalt pakitud koos või läheduses, võimaldab lehtede lõikamine, et võimaldada rohkem õhuvoolu, kaitsta seenhaiguste eest ja võimaldada lehtedel kiiremini kuivada, eriti pärast vihma või märjatel tingimustel. Põisamine aitab hoida ära haiguse levikut, sest mitmed lehed koonduvad kokku. Uusi infektsioone saab alustada igal ajal, nii et kui teete nakatunud taimi, eemaldage need - igal kellaajal. Kui näete vaid mõnda nakatunud lehte, lõigake need, lõiketera puhastage pärast iga lehe lõikamist.

Fungitsiidid on hõlpsasti lehtede lehtede töötlemiseks kättesaadavad. Taimne ja dekoratiivne fungitsiid toimib hästi, nagu ka aiahaiguste kontrollkontsentraat. Pachysandrasile spetsiifilises fungitsiidis ei pea te kulutama palju raha. Kui te pole kindel, mida kasutada, helistage kohalikule laiendustebüroole ettepanekute tegemiseks.
