Question
I noticed brown spots on growth tips ang new/young leaves of my neps. I have a few plants with this. On closer investigation, I saw orange colored insects (spidermites?, no web found on any of the plants) I checked. nepenthesaroundthehouse.com & the description of an aphid infestation sounds like the closest match. What insecticide or natural treatment do you suggest?
BTW, I live in the Philippines, my plants are in full sun. Im located 1500masl. Will try to take a picture..
Hi Jan,
I picture would help me have a clearer idea of what insects these may be, especially since you may have different pests than we have here in North America.
If you can find a systemic insecticide, it will give the longest lasting protection. I'm not sure what you have available in the Phillipines, but Acephate (Orthene) and Imidacloprid (Bayer brands) work well and are safe on Nepenthes. Neem compounds also work well, but you will need to follow the re-application schedule given on the product since it is a surface insecticide. Here's a podcast we did on safe insecticides for cp: http://www.youtube.com/watch?v=lbRCdJ8ZNF0 With all insecticides follow the directions on the package, and follow any safety rules.
Good Growing!
