is tobacco spray legal in the uk
I don't think so

Found this information.....but I still think it is very toxic stuff and best not used. Under EU legislation on sprays and things I am sure you will find it is actually illegal to make and use.
One of the top three insecticides in the 1880s, nicotine in several forms is still widely used. Nicotine comes from the tobacco plant and is extremely toxic to insects. The great advantage of home-made nicotine tea is that it is very short ived, retaining its toxicity for only a few hours after spraying. It is relatively nonhazardous to bees and lady beetles because of its short persistence.
Protection Offered: Nicotine is effective against ground and soil pests, especially root aphids and fungus gnats, and on many leaf-chewing insects, such as aphids, immature scales, leafhoppers, thrips, leafminers, pear psylla, and asparagus beetle larvae.
How To Make: You can brew your own batch of nicotine tea by soaking tobacco leaves or cigarette butts in water to make a spray. Soak 1 cup of dried, crushed tobacco leaves, or an equivalent amount of cigarette butts, in one gallon of warm water with 1/4 teaspoon pure soap added. Strain the mixture through cheesecloth after it has soaked for 1/2 hour. The solution will keep for several weeks if stored in a tightly closed container.
How to Use: For soil pests, pour the spray mixture onto the soil in the area of the stem base and root zone. for leaf pests, spray leaves thoroughly, especially the undersides. Nicotine can be absorbed by plant leaves and remain there for several weeks. to be safe, use nicotine only on young plants and only up to one month before harvest. It's probably safest not to spray nicotine on eggplant, peppers or tomatoes. While most tobacco cultivars now grown are resistant to tobacco mosaic virus, nicotine sprays could contain the pathogen, which will infect nightshade family crops.
Tobacco teas are sometimes prepared by home gardeners to control garden pests, and while not as toxic as nicotine sulfate sprays, any nicotine solution toxic enough to kill insects can also be harmful to humans”.
I think that Nicotine based pesticides (along with virtually all other pesticides) were taken off the market for domestic use some while back since manufacturers were unwilling to submit them to the very expensive safety tests that became a legal requirement.
How do I say thanks?
