Greenhouse Fumigator Buyer’s Guide
Different fumigators work in different ways to eliminate pests and fungal spores. Sulphur candles have been used for years to get rid of pests and fungal spores to prevent damage to plants. These are very effective, but they are quite smelly and you do have to remove plants before using them. Natural products may suit you better as you do not need to remove plants and they are not toxic to you, your pets or aquatic life. Some fumigators use Permethrin which is effective and less smelly than sulphur. However, it still needs to be used with care as it can be toxic if swallowed or inhaled.
How do you use a greenhouse fumigator?
You should always carefully follow the instructions on your fumigator product for safe use. In general, though the following directions should be followed.
Depending on the type of fumigator you may need to remove all plants from the greenhouse. This will be the case if you are using a sulphur candle, however, for some products it will not be necessary.
Close the windows and doors of your greenhouse.
Place the fumigator candle on a fireproof surface, such as a brick, in the middle of the greenhouse or spaced out evenly if you are using more than one.
Light the candle then leave the greenhouse, closing the door behind you. Wait outside to check that the candle is lit, and smoke is being produced. Sometimes it can be fiddly to get the wicks of these candles alight so you might have to go back in and relight it.
Once the candle is smoking you can leave it to do the job. Do not go back in the greenhouse for 24 hours if you have used a sulphur candle. After that time go in and open the doors and windows and then leave the greenhouse to ventilate.
A greenhouse is by design a closed environment that offers protection to tender plants. However, your greenhouse can also make a cosy place for overwintering insects and fungal spores. A fumigator is a simple way to eliminate these pests and provide a hygienic environment for your plants to help keep them pest and disease-free.
For a thorough fumigation of your greenhouse, I would recommend using a Sulphur Convenient Candle as it is simple to use and effective against most insects and fungal spores.
