Green Caterpillars

Started by Richard - 2066 Wednesday, 04 May 2016

I get plenty of green caterpillars on a variety on plants from herbs to succulents! I can pick them off or spray them, but they have already done their worst by then...and can decimate a plant overnight! How do I prevent the Cabbage White from laying their eggs in the first place, or the caterpillars from eating the plants? Any thoughts? R

Try using the spray Success. I believe it is a systemic spray in that it is absorbed by the plant and kills the crawlies when they eat the leaves. They don"t need to eat much before they get sick - I use it on cycads with great success (!!) although there is a little leaf damage from mature caterpillars before they get sick and stop feeding. For herbs and edibles you could try pyrethrum, which has a witholding period of a day or so - after spraying and before eating. Be sure to read instructions of course - I think Success is used only for ornamentals, not for edible plants. Have you considered a physical barrier eg mosquito net? Good luck with fighting cabbage moth - busy little bs.

Many thanks, Lloyd! I"ll give it a go! R

I try to propagate a lot of plants from cuttings in water. I generally leave them until I have a root system of 1-1.5cm in length. Now comes the problem. My success rate in the next stage is poor. I pet them into a mix of potting mix, Perlite and sand in a small flower pot and,if they fit,into one of those small commercial tray type glass houses from Bunnings with a plastic lid. Others have to go into dappled shade in pots in the garden. I"m pretty diligent regarding watering, if necessary, but the results are disappointing. What am I doing wrong? R

Dipel is good for caterpillars, it doesn"t kill anything else (ie bees) and isn"t poisonous (except to caterpillars)
