Bud rot

biggiegallz · Mar 22, 2025

Have an outdoor crop going and have noticed some bud rot today. I removed the buds that were affected. Was wondering if this fungicide will help prevent further damage. It rains alot where I am and have planted in bush area with the plants are surrounded by trees so the humidity will be high too so it was bound to happen at some stage. I sprayed the plants with a light mist and extra where the infected buds were. Is there anything else I should be doing?

It might be caterpillars causing the damage, need to be spraying bt-k. (Bacillus thuringiensis-Kustaki)
Once the rot starts, best to clip it off. Caterpillar turds are full of plant pathogens.
The Yates product might not be suitable later in flower.

Ingredients in your product:
Copper chloride , Sulfur

Citric acid/silica foliar can help reduce fungi that colonize, but wont stop a whole caterpillar turd in your bud.

Priming the plant and growing medium with beneficial fungi (Trichoderma, B. bassianna, Clonostachys rosea) induces resistance and helps protect it from common blights, but anything can have the right conditions and overwhelm the plant.
