ltd GRAZERS G3 Effective Against Damage from Cabbage White Butterfly, Caterpillar, Aphid and Other Sap Suckers 350ml Concentrate (Makes 7 litres of Ready to Use Spray), Nylon/A

This had no effect on the caterpillars, and we lost our entire crop of greens. The small print on the bottle is insufficient. Disappointed.

it does work well but the only down side you will have to use more than onece a season to affective.

I used this for the first time this year. I would highly recommend it because it works, and because of the way in which it works. I had loads of aphids in late spring to early summer on everything from containerised bamboo to young Salvias and other perennials. I used this liberally and frequently and observed plant resistance building up over time. I used it when plants were young and in rapid growth and had stopped using it by July, when everything seemed mature enough to cope and my desire to encourage wildlife overcame my desire for pristine plants. I try to be as wildlife friendly as practicable so I'm a gardener who is happy to live with some plant damage. In the case of aphids and their ant farmers, I left a couple of hardier plants untreated. The slug version works really well too though there is anecdotal evidence they'd simply moved to my neighbours garden.

Even just a few days after applying this, without any rain, the white winged marauders were hovering around my purple sprouting broccoli, which are protected already from pigeons. They still settle on the leaves. As I only have a few plants to protect, I can visually inspect them. So far several caterpillars removed as well as some clusters of eggs. So does it work. Maybe...

Used Grazers G3 on my tomatoes and other plants all summer - fantastic stuff if you use it preventatively and regularly - I had a virtually aphid-free season once I started with this, and no worries about toxicity or harm to friendly bugs. Tomatoes tasted great too. After the first spray bottle purchase (from a garden show) I carried on with the concentrate for economy - think I went through 2x350ml over the season, so good value. Bought this in autumn so I'm ready for next spring.

I used exactly as instructed, I was very careful about the measurements. This killed all my plants and the bugs are still thriving. Had to throw out the plants, really upset because up until they got the aphids they've been thriving. The seeds weren't cheap and took a long time to come, really upset at how terrible this stuff is. The aphids are still fine. DO NOT USE.

The product was effective on my nasturtiums, I used every third day. Unfortunately the spray bottle only lasted a couple of refills so I will have to get an alternative spray

I have used this product for the last 2 seasons and I've come to the conclusion that I may be wasting time and money on something which doesn't seem to work very well, if at all. The cabbage white butterflies seem to have no aversion to treated leaves and even leaves which were dripping with the treatment still get covered in eggs on a daily basis so I'm manually removing eggs. Going forward I think I'll not be buying this again and will use garlic water instead in conjunction with a physical barrier (fine netting) to keep the butterflies away from the leaves. I've got a nation of garlic to use up so plant protection will be a great secondary use for the garlic. As far as this product goes I'd say don't bother...
