What do you have for a bad infestation of psyllids? They were in my orange trees last year but now they seem to be moving. I’ve got several trees with activity and I wanna get rid of them for good. The home depot spray didn’t kill them for long and they’re back. can you help?
Psyllids are in the “leaf hopper” family and prey upon the sap of host trees. They’re mostly species specific so to have them move from your orange trees to another species? That’s not common and kinda unusual.
So what makes this pest particularly challenging is that the adults lay eggs “inside” the host tree’s foliage. Once the eggs hatch, they feed inside the leaves and traditional pesticides won’t reach them. For this reason its best to treat them using a good systemic like PROTHOR.
Prothor uses the same active as products like Dominion but its unique design enable it to be more “soluble” and therefore more readily available for plants to absorb. This is a big factor if you plan on using it as a systemic.
Prothor is also very “clean” and refined. Its water based and super “gentle” on stressed trees and shrubs. Its active is super stealthy and not detectable so as you spray, targeted pest won’t know anything “bad” to them is being presented.
.
Prothor is also unique in that it can be both sprayed on the affected trees and shrubs AND be used as a systemic.
So first, mix .5 to 1 oz per gallon of water and spray down all the foliage you can reach with the mixture using a good PUMP SPRAYER.
We suggest you add some SPREADER STICKER to the mix; 1 oz of Spreader Sticker with every 1 oz of Prothor you mix. The Spreader Sticker will help the treatment “penetrate” the affected leaves ensuring the larvae don’t survive.
.
.
Now if you don’t have a good PUMP SPRAYER to reach up where high enough, get our 6 GALLON HOSE END SPRAYER. This sprayer works using the power of your garden hose water pressure meaning it will generally spray very high.
.
To reach the maximum height potential of the sprayer, remove the black tip on the sprayer nozzle. It pops off easily. Now it will spray a straight “laser” like beam of water a good 20-30 feet up ensuring you reach all important areas where the psyllids might be living.
.
The mixture of Prothor and Spreader Sticker needed will be 1:1:128. So effectively 1 oz of Prothor in the sprayer means you’ll want to add 1 oz of Spreader Sticker and then some water. For most treatments, you’ll want to add 3 oz of each and then fill the sprayer 1/2 with water. Next, hook it to your garden hose and spray away. Remember, you’ll need to keep one of your fingers over that little “hole” on the top of the sprayer to make sure the siphon effect is working. This is all covered in our video here:

.
One thing to remember: Only treat in the evening! This insures the treatment sits overnight and “locks” in to the foliage providing maximum protection.
.
The day after you treat the foliage, mix up some of the Prothor to be used as a “soil drench”.
.
The rule here is simple; 1 oz of Prothor for every 10 inches of tree trunk width. Using a 5 gallon pail, add the needed Prothor, stir it up and then bring it to the tree you need to treat (you won’t need any of the Spreader Sticker for this application).
.
Using a Pick Axe or a stake of some kind like a piece of rebar, make 8-10 holes around the tree trunk within 3 feet but not closer than 1 foot of the infested plants trunk. Holes should be 6-12 inches deep and wide enough to accept the “pour” from the bucket so the mixture goes down the holes and not away from the affected plant.
.
If done correctly, the treatment done to the plants foliage will kill all the exposed stages within 1-2 days. But since most of the psyllids will be “inside” the foliage, you will need to spray once a week for 4 weeks so that no pupae hatching will be able to thrive (the pupae can’t be killed by the spraying or the systemic treatment). By the end of 4 weeks, the systemic action will kick in and start killing all the hatching/feeding larval stages and by 6-8 weeks, the problem will be gone for good.
Follow these directives and you’re psyllid problem will soon be gone for good!
