We live next to two kiwi fruit orchards, and have just had messages saying they’ll be spraying Hi Cane soon. They do give us at least 24hr advanced notice. It’s potentially dangerous stuff, we will not go out of the house during any spray time.
That’s a good question. The health effects of the previous product have caused serious questions for a long while, so one might guess the new product has been developed to cause far less issues in side effects, yet still be effective in its action.
