Vid hög luftfuktighet kan grå form infektera en rosmarinväxt på bara 20 timmar.

Doftande rosmarin (Rosmarinus officinalis) är en mångfacetterad ört. En ständig i US Department of Agriculture plantera hårdhet zoner 8 till 10, rosmarin är en kulinarisk häftklammer. Som en prydnadsväxter är mogna rosmarin en torktolerant ständiggrön buske som kan bilda häckar eller jordklot. Inhemsk i Medelhavsområdet, rosmarin blommar i områden med torra, heta somrar, och den kan utveckla mögel i fuktiga miljöer.

Känn källan

Grå mögel, även kallad botrytisblight, orsakas av Botrytis-arter svamppatogener, oftast Botrytis cinerea. Sjukdomen gynnar vått väder, fuktiga klimat, skumma platser och växthusmiljöer. Kall, regniga fjädrar, där temperaturen svänger runt 60 grader Fahrenheit, skapa en idealisk inställning för att grå form utvecklas. Sjukdomen sprider sig lätt när vatten sprutar från en infekterad rosmarinväxt till närliggande, friska växter. Grå mögel kan infektera rosmarin nålliknande löv och dess woody stammar.

Leta efter bevis

Grå mögels gemensamma namn antyder sitt primära symptom - en fuzzy, grå tillväxt som sprider sig över plantans ytor. Denna "mögel" är faktiskt det sporade skedet av sjukdomen. Innan sporerna bildas, börjar sjukdomen typiskt som bruna fläckar på löv eller lesioner på stjälkar. Bladen kan krulla, bli brun och viss. Svarta strukturer som kallas sclerotia kan övervintra på död rosmarinvävnad. På blåsiga dagar, eller om du skakar kraftigt smittade växter, kan ett moln av dammiga sporer stiga upp.

Bryt cykeln

Grå mögel utvecklas genom olika livssteg. Under vinterns vilande stadium lever sklerotia och svampmyceli under plantorna på droppe löv och stjälkar. På våren producerar sclerotiaen och myceliet sporer som kallas conidier som smittar växter. Att riva de fallna skräp under plantor på sensommaren till hösten stör störningen av gråmassens livscykel genom att förhindra att overwintering sclerotia och mycelia förfaller till deras nästa steg. Skräpet är inte lämpligt för kompostfacket. du ska kasta den i en soptunna eller bränna den.

Hantera Mögel

När du ser symtom på gråmögel är fungicider ineffektiva för att kontrollera sjukdomen. Cornell University rekommenderar inspektion och sanitet som bästa hanteringsmetoder. Växla rosmarin genom att lämna utrymme runt det för att luften ska cirkulera fritt och undvika att blöta bladen genom överhettning. Skörda eller beskära rosmarin bara efter att morgondugg har torkat, och raka inte de fallna skräp under växter om det är vått. Använd beskärningsverktyg som du desinficerar med en lösning av 1 del blekmedel till 3 delar vatten.
