Orothonex/fungonex question
I am a recent (one year) addict to roses. I sprayed with funginex because
my nursery connection said it was better for blackspot, rust, etc. Now my leaves are being eaten alive. Should I be using othonex instead of fungonex, and how often do I need to spray? Only did it once in the spring, and they are all still pretty disease free. Most of the problems are with lover leaves turning yellow/brown. I have LOTS of butterflies. I heard they lay their eggs on the underside of the leaves so the newborns can eat when they hatch. Please help with bug problems and spraying questions. Thanks |

Orothonex/fungonex question
Arlene,
My experience with roses pales in comparison with that of most people on this newsgroup, but here are a few points: Orthonex *contains* Funginex (Ortho's brand of fungicide) and Orthene(?) (Ortho's brand of systemic pesticide). I've been spraying my roses (in Zone7b in humid North Carolina) every 7-10 days since March or April. I understand that many rose growers use fungicides on a regular basis, but pesticides only as needed. (But I didn't read that until I had already started my Orthonex regimen.) I have no idea whether butterflies lay eggs on rose leaves; I always thought they laid the eggs directly on or near the "more desirable" caterpillar food such as parsley, etc. (In fact, I've read that some people actually plant parsley strictly for the butterfly caterpillars; in my case, I planted more parsley plants in the hopes that some of them would escape the notice of the caterpillars.) I have never seen a butterfly near any of my (admittedly few) roses. This year, however, despite my first-ever Orthonex-spraying regimen, I have at least as many butterflies as in the past few years, despite my having no "caterpillar" plants (parsley, dill, etc.) and the same 2 butterfly bushes that I had in the past. My suggestion is for you to ask local gardeners. Also, if you could give us a general idea where you are (region & garden zone), I'm sure that there are people here who might be able to give you some good advice.

Orothonex/fungonex question
In article et, "Arlene
says... I am a recent (one year) addict to roses. I sprayed with funginex because my nursery connection said it was better for blackspot, rust, etc. Now my leaves are being eaten alive. Should I be using othonex instead of fungonex, and how often do I need to spray? Only did it once in the spring, and they are all still pretty disease free. Most of the problems are with lover leaves turning yellow/brown. I have LOTS of butterflies. I heard they lay their eggs on the underside of the leaves so the newborns can eat when they hatch. Please help with bug problems and spraying questions. Thanks Orthenex is actually a combination of two Ortho products.... Isotox (for insect control) and Funginex (for fungus control). The mixture in Orthenex is only half strength of the two. When I used Isotox, I had no (and I mean NO) insect problems! Isotox is an 8% solution of an ingredient called Acephate (in Orthenex it is diluted to 4%). Funginex is a 6.5% solution of an ingredient called Triforine (in Orthenex it's diluted to 3.25%). The only reason I now use Orthenex is that I got a bottle as a gift (it's really expensive). It makes it convenient to combat both insects and fungus using only one spray can. The only problem I've had with it is when I sprayed some roses I had transplanted earlier in the day and the leaves died (the stems remained green). I should have waited several weeks for the roses to regain their strength after the transplanting. I spray it every 2 weeks. My Ortho rose book states that rose leaves turning yellow is a symptom of oxygen starvation. Roses get their oxygen from the soil via their roots. The book states that overwatering can cause the soil to become muddy which makes it impossible for the roots to get the needed oxygen....hence the yellow leaves. Maybe you should reduce your watering on a trial basis to see if it improves. Just my 2 cents worth. Only been at it a year. elfa zone 9 (north of San Francisco with hot dry summers) |
