Battles Sulphur Candle 225g PACK OF 2 - Kill Greenhouse Pests and Spores

Product Information

The alternatives seem to be all permethrin based which would kill all crawling/flying insects in the greenhouse but not eggs or fungi - at least as far as I know. Since there isn't much flying or crawling around in it in February/early March it would seem to be a bit pointless.

Garlic Greenhouse Candles as recommended by Adam Pascoe in the Gardeners World magazine– “Take this opportunity to clean the glass & framework & fumigate to get rid of any pests & fungal spores. Try a Garlic Candle from Green Gardener, which produces smoke that gets into all the nooks & crannies. Use 2 candles per greenhouse. Seal the windows and doors, so the smoke does not escape.”I'm little confused as to how safe it is to use a Sulphur Candle. I have frogs, newts etc. in my polytunnel and I don't want to deliberately kill them. Especially as the frogs will eat slugs etc.

The ingredients are not listed, but I have used Provado ultimate bug killer, "Growing Success" Greenhouse Whitefly, and some VERY old nasty stuff of my farthers called Symbol 2 which contains pirimiphos - methyl.Funny things 'green'houses. Why are they called 'green' houses, when they are clear glass ? ? They're certainly green , with slime and moss at certain times of the year ! I have just cleaned the panes yet again, of said slime, cleared moss out of the recesses for the glass, and all looks pretty good. This was done with vinegar and warmish water, a plastic label for the house frames, and a good stiff scrubbing brush to give a good finish. Monty Don would be proud of me ! So, leaving out a top pane from the end of the hoosie, for cooling purposes and insect in and eg-ress, I look forward to another season of rotting seeds, non- appearance of seeds, curly tomato plants, unexpected visitors in the seed trays, like carrots with toms, cabbages and broccoli, PANSIES (Where the hell did THAT one come from ?) and unidentifiable bean family wayfarers. It's like a boarding house for homeless seedlings here ! We have a 30-day return policy, which means you have 30 days after receiving your item to request a return. Fumigation pest control is important as pests and diseases can thrive and multiply in the warmth and shelter of a greenhouse and once established, may be difficult to eradicate. The key to avoiding pests and diseases is to maintain a clean and tidy greenhouse while keeping a sharp eye out for problems so that you can deal with outbreaks whilst still in their early stages. An annual cleaning will help to control pests and diseases. Ideally, clean your greenhouse before spring sowing - whilst the greenhouse is at its emptiest and this will remove any over-wintering pests and diseases. If you reuse compost/soil from the previous year, then you may wish to consider sterilizing the compost before you use it again. A Soil Sterilizer will kill off any insect eggs in the compost.

But now its getting very difficult to source sulphur candles as they are now banned for use on plants as a pesticide although interestingly they still can be used as a greenhouse cleaner which is what I use them for. However companies that make them have decided not to bother with re-registering them due to the extra cost and have ceased manufacture Avoid breathing the fumes from a burning sulphur candle as the Sulphur Dioxide (SO2) that is given off will irritate your nose and throat, irritation will also occur on the moist surface of the eye. Blight: The spores of blight infection can easily spread to tomatoes and potatoes from plant debris left in the greenhouse or garden, so it must be removed and disposed of or burnt.A greenhouse is a wonderful addition to almost any garden. It enables you to grow tender plants earlier, ripen crops that need more warmth and keep harvesting later in the season. Unlike other garden protection such as cloches and row covers which need removing whenever you want to weed or water, greenhouses make tending your plants much easier. However, it’s not just plants that enjoy the protection of a greenhouse – pests and diseases love them too, avoiding the harsh weather and frosts that usually kill them off! So how do you stop them from enjoying a sheltered existence where they can strike at your new sown plants? The answer is a good spring clean...

Red spider mite: The hot dry conditions in greenhouses over summer are ideal for red spider mite which multiply rapidly, reducing the crop of many plants. The tiny red female insects can overwinter on greenhouse walls and pots so it is important to clean them out thoroughly. Cleaning has never really been my strong point (as my wife would gladly tell you) but when it comes to the greenhouse it is an essential part of the gardening year. Once Christmas is out of the way and days start to lengthen, cleaning the greenhouse is a great way to feel connected with the garden again, even if the temperatures are too low to be sowing seeds. Northumberland can be unforgiving on a north sloping face, but this only means that we are about a month behind the rest of the country, and possibly three weeks shorter growing season. The soggy ground will soon dry out to entice me in to thinking that I can start sowing a month before it is wise to. Listen to the old fellers and when THEY start digging and sowing !"
