i just got back from my local nursery and i was there looking for azamax , they didnt have it so after an hour of reading labels i happened to notice two little boxs in the corner on the very back of the shelf , covered in dust with their coloring faded, i go to this place atleast once sometimes twice a weak to take my daughter to look at all the flowers and stuff they have , and i pretty much always stop and look at their nutrients and stuff , but i had never noticed this before and it just so happens that i am having a war with spider mites right now so when i read what it was i had to buy it , its called "Black Leaf 40 Garden spray. Also it says on the box "The original nicotine sulphate solution. says spray flowers, shrubs , vegetables and trees. apparently it is also used "on the farm for poultry to control chicken lice and feather mites.has anyone used black leaf?
