What makes citrus so different re Confidor?

Thanks for the prompt response to my query re using Confidor on citrus. I do understand current regulations but I don't understand why citrus is any different than other edibles on which Confidor can be used as long as the withholding period is applied. Based on the 15g/l of Imidacloprid in Confidor Lawn & Garden, the one litre I used diluted at 20g/3l, would have applied a total of .001g to the three trees I sprayed. While my scientific expertise doesn't extend to horticulture, I find it hard to believe this .001g used this way can be such a worry, especially since it was rinsed off and further diluted(by probably at least several orders of magnitude). Please advise what makes citrus so different.

Answer: Hi Larry,

Thanks for sending through your question.

Yates Insecticide is a systemic insecticide. This means that it enters the plant, stays within the system of the plant for a period of time acting on those animals that ingest the plant matter. Confidor is not really washed of as much as it is metabolized in the plant over a period of time.

As you can understand because of this action it is not easy to get registration from governing bodied for edible type crops.

The decisions for Confidor being registered for crops is made through extensive testing via the governing body in Australia – the APVMA. They are responsible for allowing or disallowing registrations of chemicals for safe use on plants. And as such we can not legally recommend the use of any product for a pest, disease or plant that it is not registered for.

I can’t specifically say the exact reason for Yates Confidor not being registered for use on citrus however it will most likely be an incompatibility regarding the crops physiology and the chemical.

If there is anything else I can help with please let me know.
