any systematic spray for chewing insects will get rid of aphids, but ants also eat aphids

g'day,

you will robably find you have the aphids because you have ants, aphids don't need heavy handed approach they can simply be sprayed off the plants with a strong spray from the garden hose, or spray them with soapy water.

i realy wonder at how much damage can aphids realy do to a healthy plant ok the for those roses they may make the flowers look spotty but then how important is that in the bigger picture? or they can create some sooty mould unsightly maybe but not that detrimental citrus fruit full if sooty mould still taste the same, again they can simply be hosed off.

but if the ants are there then you need to move the ants on or the aphid issue will persist. another way is if they are on trees/shrubs like citrus or roses put a smear of vaseline around the trunk to stop the ants walking up the trunk, be sure that no other part of the plant touches anywhere else that the ants can make alternative route to bypass the vaseline.

Whenever I've had aphids, I used Safer's Insecticidal soap. Note that many of these products suggest that you apply out of the sun or you may get leaf damage or drop. If you have a spray bottle, you could also try holding the branches over a bucket and blast the aphids off with water. The adults fly in and will lay eggs which hatch to produce the aphids that you see, so it doesn't matter that there's no vegetation nearby. I'm up on the 18th floor of a concrete building, way above the trees and get aphids. :-( Also hope that you start seeing more of these: This is a ladybug larva I took a picture of last evening. These little hungry guys dispatch of aphids like there's no tomorrow. If you see any of these, try to move them to the infestation.

Hi Tiesa and riap, I sometimes use BATs, too. If you water it in, you're using it as a drench and enabling it's systemic quality. It will take a while (up to a month) to travel through and treat all of the plant. I would not repeat as too much will negatively affect the plant. You can also spray (Outside), too. If you only spray, you should repeat in 7-14 days to eliminate any newly hatched insects. Gail

Have you ruled out a nutrient deficiency? I'm not super experienced but it kind of looks like a phosphorous deficiency to me since the leaves are turning such a distinct shade of purple on the third photograph down. Like I said though, I'm hardly an expert. And I'm not sure if the deficiency would also cause that yellowing, so you may be dealing with a different issue.

I believe they must be some kind of flea beetle, thank you for the information on them Dave, I've never seen them before. i saw them for the first time about 3 weeks ago on the kale, pulled up almost all of the kale and what was left seemed OK until yesterday, now covered too. Will be washing it off and harvesting it all and then removing everything from that garden. I may have to get some kind of spray if they spread to the other gardens. Wish I could burn but we have a fire ban here due to the dry conditions so will be bagging and waiting for rain before burning them. With the mild winter, no snow and hot spring I'm thinking I better get used to bugs! Here is a close up of the beetle.

what about the ants? no good treating the aphids and not the ants, ants first then aphids will be easy. grow native plants they aren't as susseptable to things like roses are.

again how much damage do they realy do? saw an old lady in her garden last night on tv showed her watering her roses all with planty of aphids on, the flowers looked good to me.

The aphids are having a great year and seem to be on everone,s
roses.We use a pyrethreum diluted to manufacturers instructions.I only spray the stems and not on a hot day,preferrably at dusk.we (me and my neighbours)and everones roses are looking great.As you say its dificult with water restictions to hose them when you want and squashing them is a slow job For ants we use euctalyptos spray from household disinfectant.diluted as per instuctions.also as mentioned by Len vaseline on the trunks is good
good luck and aphid free roses chas

Just an FYI for those who do not know.... Ants do NOT like cinnamon, for an inexpensive & natural way to be rid of them. I saved my apple tree from them by inserting a few cinnamon sticks in the ground at the base of the tree. My husband was shocked at how well it worked! Hope it helps you, too!

White oil is the answer for aphids its garden friendly and harmless to all living things .You buy it at your garden suppliers and follow directions When you spray make sure you spray over and under the leaves .The white oil smothers the aphids.Another thing to note as long as you have aphids you will have ants as they farm them .The aphids exude a sweet substance the ants love .I always made my own white oil using any vegetable oil but its easier to buy it .Good gardening.

Hi. A couple of weeks ago I had the best time watching aphids on one of my roses. It was smothered in aphids, so much so that from a couple of metres away it looked as if the stems had a velour coat. There was so much honeydew from the aphids (that sweet substance others have mentioned) it was dripping from the leaves. I felt very tempted to spray but held back, remembering last year how hoverflies had cleaned up my aphid problem. This year the ladybirds led the assault, with hoverflies and predatory wasps backing up. I haven't sprayed that rose and it, and all my other roses, look fine.
Please keep in mind that when you spray for aphids then you are very likely to be also killing those wonderful natural enemies of the aphids: ladybirds, hoverflies, lacewings, predatory wasps.
I don't know how much damage they are doing to your roses, but maybe a little bit is acceptable when we let nature take care of the pest problem.
