I'm not familiar with this variety, could you explain what is different from the regular coerulea? Cheers, Math

In Peru, there is an enterprise commercializing biological control probiotic. I might try these products: - Bio-Splent 70 WP -> Bacillus subtilis AP-01 (https://silvestre.com.pe/productos/bio-splent-70-wp/) - Tricox -> Trichoderma koningii, Trichoderma harzianum...

So far, I have not had much luck with the fungicides I used. However, the link @richgarrison provided have recommendations for molecules to use against anthracnose.

It does look like anthracnose! I will try to get my hand on the the suggested fungicides. Many thanks!!!

I still have hope one fellow ST members who previously encountered this pathogen , and who got to the bottom of things with it, will chime in. @awesomei are you also growing your plants in the tropics?

Can I get in line for the next division? :D

I wonder if some preventive probiotic treatments (Bacillus or Trichoderma) would be a solution here.

If flasks are available at some points, I would very be interested. I can pick them up in the USA.

Same here, side by side are affected plants with perfectly fine ones

I have a sangre de grado tree in Tarapoto I could use to collect the sap. However, I would very be interested in identifying this pathogen and learn about ways to prevent it. I use both city treated tap water and the water I collect from the mountain creek next to my greenhouse. The problem...

This is a plant I received as a single growth 2 years ago. It was then a well established plants about with a leaf span of about 20/25cm. It grew extremely quickly for me and rewarded me, a few weeks ago, with 3 very nice flowers. Looking closely at it, I found the flowers are not as dark, and...

Hi everyone, for the last two years, I've been struggling with what appears to be a fungus attacking the leaves of my Paphiopedilums. I live in the French Guiana Amazon and the climate is very humid! I grow all orchids under a 50% shade house and my shade house is quite ventilated. However, each...

Welcome, I grew up in Montreal and my whole family still live there! I now live in French Guiana. Math

I saw it too and found it amazing!!! Do you know which nursery sell this cross in EU? Cheers

So far so good with the lueddemania. This plant was purchased as a seedling about 2 1/2 years ago!

Hi everyone, so the thing is I live in French Guiana and this plant is endemic to the Guiana plateau. Basically it grows naturally here. Yet it still is a rare plants and few have found one (when not in flower, they are nearly impossible to see in the middle of the dense vegetation). This plant...

Much more cute and amazing than I initially expected! This is a native from French Guiana! The whole plant is very elegant. Enjoy

Amazing! How long does your bloom last usually? I have one that bloom every year but my flowers don't last more than 7-10 days. Most likely due to warm and humid weather. Again! Congratulation

Magnificent!

Merci Xavier pour ton retour. It appear I still have a lot to learn! Growing orchids in an amazonian climate, next to primary forest, has proved to be both challenging but also very interesting and rewarding! I just checked my fertilizer bag and I was lucky the label hadn't disappeared yet! Here...
