FL & other southern states

Anyone else notice (especially fl) a spike in mealybugs & scale this year? I'm seeing a big increase this year with mealys on crotons & hibiscus & scale on Ind. hawthorns.

The folks from up north must be bringing scale with them on the cars and feet. It has been terrible up here this summer

We had a wet year and therefore a lot of scale. Pink Hibiscus Mealybugs are on the rise and will attack Ligustrum japonicum as well as other species. Google Pink Hibiscus Mealybugs and the U of F will pop up first. They say there is no Chemical control of Pink Hibiscus Mealybugs the same as they say there is no chemical control for Cycad Scale other than fish oil. I have some Ag side chemicals left over from when I had a Nursery, They work but are not legal for residential. Your best bet is to use Granular Merit just at the start of Rainy season at the same time you would apply a slow release Ornamental Fertilizer. Merit is not going to control Pink Hibiscus mealybugs but it will suppress them. Remember Merit takes a while to get into the plant and is more for prevention than curative.

Thanks Ric. I googled PHM a week or so ago & already seen the note that UF said about no real treatment other than try oils.
And yeah we did have a pretty good summer as far as rainfall. I'll make a note to try Merit next year.

Though meally bugs haven't been bad up here I came across an oak tree the other day, approx. 10 feet tall that was covered with them. It looked like snow on the bahia down wind from the tree.
Scale has not been that big an issue here compared to years past. Even Asian Cycad Scale populations are less than they were 5 years ago.
We are seeing chili thrips becoming a problem on many types of ornamentals and even weeds. If we could only train them to kill the weeds we would be in good shape.

I will definitely agree with Ric. We have been using the Coretect tablets which have the same AI as Merit.

On a condo right next door to one I treat was an Oak Tree covered with cottony cushion scale so bad that it looked like snow. There was fall out on my turf down wind of the tree. Even if the tree isn't my responsibility it is very near the line so I sprayed it.

Chris

Yes Coretect is a lot more cost effective than Merit and works just as well. Clearys Tri Star is a WSP that has a quicker knock down but not the residual. I have been using Tri Star this last year and will be adding Coretect on certain plants to be darn sure.

I have only begun to scratch the surface of my customer base on offering ornamental tree/shrub care. Mainly because of lack of equipment. However, the dozen or so landscapes I maintain, Merit is a staple. I apply Merit .5G along with a slow release granular fert in the Spring(just as Ric suggested). It gives me season long control of lace bugs and pretty much controls everything except spider mites. I have had to spot treat for bagworms on a couple of occasions but in my opinion Merit(or product with same ai) offers excellent results. I think the trick is timing. I've wondered if using Merit as a soil drench might offer better results but again, I lack the proper equipment.

Why not use Mallet @ about $1.00 per pound?

Now that imidacloprid is off patent it is produced under many different label names. Mallet by Nufarms being only one of many.


Ted

Because of the sandy soil in my area, I have found no advantage (in fact a disadvantage) to injecting imidacloprid or drenching it. Granules leach slower and therefore work better in sandy soil. However you may have heavy clay soil where root injection would work better than a drench. Root injection doesn't take a lot of high priced equipment. I have one type of root injector that is used for both Termite and Deep root injections and don't use it very often now that I no longer do Termites. But you can make an injector out of Galvanized Pipe real cheap and using a skid sprayer. But there are self contained injector that work great for spot treatment and low production rate.

About 45% of my business is Ornamental and it has a higher profit margin than turf in my case.
