When is Flower withering Most Active Period on Red-crescent marigold?

Flower withering is most active in late spring and early fall when humidity levels increase, creating a conducive environment for the pathogen Botrytis cinerea to thrive.

Infectivity

Highly

As Botrytis cinerea reproduces through spores which can be easily dispersed, the disease can spread quickly through a population of Red-crescent marigold.

Lethality

Moderately

While not directly lethal, the disease diminishes the plant's vitality and can lead to death if left untreated.

FAQs on Red-crescent Marigold

Does flower withering affect only the blooms of Red-crescent marigold?

Primarily, yes. However, prolonged disease conditions might weaken other plant parts, impacting the entire plant's health.

Can Red-crescent marigold recover from a flower withering infection on its own?

Without effective and timely interventions, the plant might not recover and could eventually die.

Why does flower withering occur more in high humidity?

High humidity levels provide conducive conditions for the spore germination and growth of Botrytis cinerea, thus intensifying the disease.

Is there any natural defense that Red-crescent marigold has against flower withering?

Specific varieties of Red-crescent marigold might be bred for disease resistance, but general specimens lack an inherent defense against flower withering.

Can flower withering spread from Red-crescent marigold to other plant types?

Yes. Botrytis cinerea can infect a wide range of host plants, not specifically limited to Red-crescent marigold.

Does a single wilted flower mean my Red-crescent marigold is infected with flower withering?

Not necessarily. One wilted flower isn't conclusive proof. Monitor for consistent patterns or other symptoms before diagnosing with flower withering.
