You could try and apply micronized sulfur. Its a fungicide technically but the scent and taste alone may detour them from eating it.
A few things to consider.
1. This product mixes best with HOT water. Once blended in you can ADD COOLER water to balance things out.
2. The solution needs to be sprayed through a nozzle with a very high micron count, the smaller the droplet size the better. A regular pump sprayer won't do nearly as good a job.
3. DO NOT APPLY DURING FULL SUN / HIGH NOON. This will fry your entire crop. Wait for overcast conditions, the Florida sun will be tough on them.
4.DO NOT APPLY if you have sprayed any other IPM or foliar spray that contains oils of any kind!!! This chemical reaction will also fry the plants foliage. I would wait 3 weeks to apply sulfur if this is the case or vice versa. These oils stay around longer than you'd think.
I have used this exact applicator with Sulfur and it does wonders.
