After tending to the crop for weeks Hayley harvested the lettuces and removed the leaves one by one. She then rated the damage visually and useda leaf area meter for the first time,to record the damage in every square cm of the leaves. Use this attractive, dual purpose Butterfly House and Feeder to offer butterflies food in the summer and shelter in the winter.…

Efficacy and environmental fate of copper sulphate applied to Australian rice fields for control of the aquatic snail Isidorella newcombi I imagine barrier efficacy might depend on the width of the barrier and skinnier tapes might be less effective barriers than 5″ of mesh. I have yet to try using any other type of mesh (steel, aluminum) but if I get bored that might be a fun experiment. I also imagine in addition to whatever theoretical chemical/electrical property copper has that slugs don’t like, there is likely a mechanical component because irregular wire loops might be irritating to ooze across and there may be some variability in effect based on the size/configuration of the wire in the mesh. So pleased, daren’t put anything outside, especially with all the rain we’ve had without the tape. We tried it last year for the first time and it really did work. Thanks again. Copper DOES work as a slug and snail barrier if the percentage of copper alloy is high enough and the width is in excess of 4 cms.”It is the tiny electromagnetic charge a slug or snail feels when it tries to cross Copper Slug Tape which prevents them from reaching the plants and crops. If you want to protect your plot from slugs and snails, these trialled remedies just won't cut it. You may need to try something different. What can I do? While this research hasn’t shed any light on what you can do to obstruct slugs and snails, it has at least shown that these barriers can be unreliableand ineffective. Great to see… to add to the video list, I liked this one on the topic: http://www.youtube.com/watch?v=ZFn9TT_rlXU

Encourage their natural predators into your garden by creatinga haven for wildlife, such as birds and frogs. Some products may be delivered straight to your door from one of our suppliers and these products will be labelled within the product description.Lettuces planted in the ground were found to be more susceptible to slugs, with 5.7% of each eaten on average. This compares to just 0.2% of those in pots, which, despite this advantage, yielded less crop. Of the thousands of enquiries received by RHS Gardening Advice every year, deterring slugs and snails is atop concern. To ensure we aregiving the best advice on this much-debated topic, we set up a project – Gastropod Barriers– to test whether the most commonly recommended home remedies really work.
