Cases of Powdery Mildew Attack!

Recent weather has been warm and then cold and then warm and then cold with scatter rains. Some mornings were wet and cold and followed by warm afternoons. I had to do a bit of work moving pots of more delicate herbs/plants into the mini green house and out into the sun and vice versa.

The curry plant has been growing quite well but I was surprised that it has invited unwanted guests such as tiny caterpillars. There were also clusters of webby tiny black eggs mainly towards the ends of stems where the shoots are. Most of the stems which are strong and healthy but exposed to air did not have these webby eggs. The eggs were found in areas where the stems were very congested and hidden. I had to snip off several stems as a result. Guess I learnt a lesson : prune the plant on a regular basis to allow better air flow between the stems.

My pot of mint which was potted on last Friday has got powdery mildew. I think placing it in the green house with all the condensation has caused this. I removed several leaves and sprayed a few infected areas with Mancozeb Plus. And quarantined the pot in another area of the garden. Will have to do a re-spray after 10 days. I have successfully gotten rid of powdery mildew on two other pots of mint but not the vine which was growing under the shelther. The condition was so bad that the vine is already succumbing to its invader. The common mint which was potted on last Friday.
White powdery mildew on its stem.
White powdery mildew patches on one of the mint leaves.
The grape vine is almost dead due to powdery mildew.
Powdery mildew patches on one of its leaves.
The oriental radishes are looking stronger and bigger. Hoping to harvest some crunchy yummy roots soon.
The purple king bean plant has leaves that are turning yellow. I am assuming that it is due to the colder weather coming as it does not survive winter. This bean plant is really running behind time due to the heat wave in summer. It has put out a lot of beans and I am going to let some of them stay on the vine to mature for seed collection.
