I am not arguing with anything said above, just providing a little more info....
The Vitality Plus sold in Australia is not systemic and can be safely used on food crops. It's active ingredient is ISO1750 approved and concentration for LD50 equal approximately 350mg/kg of pure organic active material - this is equivalent to 1,500 litres in one dose. In Australia, it is sold as a plant conditioning spray and does not require warning labels as it is non toxic. I don't believe it contains Thiamethoxan, but it does contain a Macrolytic Lactone. Abamectin is a Macrolytic Lactone but Vitality Plus uses a single active product, but stereo chemical configuration gives it numerous properties. In its concentrated form, the product is highly toxic to bees, fish and invertebrates their eggs and larvae but is completely non toxic to bees after 24 hours of being sprayed on plants. It is completely bio-degradable and has low to negligible bio-accumulation potential not persistent in soil and on plants. The solution sold as Vitality Plus in Australia is extremely diluted, so the information above should also be diluted proportionately.
Take from this what you will...
