This method of control has worked in some cases.
Salvinia in Caddo lake is being controlled (or somewhat controlled) by importing weevils from S America to eat them.

I heard a rumor when I worked on the lake in HS that there was a recommendation to put 3000 in the lake and they put 30,000 instead. I remember seeing them all up along the bulkhead everytime the grass got cut and clippings went in the water.Troutslime said:
How about the triploid grass carp put into Lake Conroe by TAMU?
That's a very bad idea.shiftyandquick said:
Beekeepers are against this as Chinese Tallow trees are hugely significant sources of nectar and honey in Texas.
But the Timber folks I assume would support it.

Can we give them mesquite and juniper?
Yeah that worked out so well that the professor heading up the project left for north carolina shortly thereafter.spicyitalian said:I heard a rumor when I worked on the lake in HS that there was a recommendation to put 3000 in the lake and they put 30,000 instead.

european carp, asian carp, tamarisk, the aforementioned chinese tallow, johnson grass, etc, etc, etcOrnlu said:aggiedent said:
When are we ever going to learn. Every time the powers that be try something like this, it creates an even bigger unforeseen problem.
When have we tried something like this before? I know about a bunch of invasive species, but I don't know about any intentionally introduced species.
huh, I get good results by girdling and leaving them standing for a year.iamtheglove said:
I'm skeptical that releasing these 2 insects will solve the Tallow problem without creating many new and unknown issues.

Burning, pesticides, etc don't really work and once it gets a foothold it outcompetes the native trees. The recommended treatment is to chop down the tallow tree, drench the trunk in pesticide and then mow constantly around the perimeter of the trunk to take out root shoots. Even then the seeds, which a single tree can produce over 100,000 a season, can lay fallow for up to 7 years in the soil before sprouting. This is a bad, bad tree and will overwhelm most every native it encounters.
Do you mean to tell me that johnson grass was introduced intentionally? WTH?Quote:

It looks like they have had decent success at slowing down salt cedar in west Texas with beetles. Hopefully if they've done proper research we can deal with tallow and not create a bigger problem down the road.

A few points I would like to weigh in on here:
A. I can kill the **** out of every tallow I find with several different methods and chemicals. Que up the Arsenal and go to work. However tallows are super prolific and unfortunately wont ever be eradicated.
B. We had bees when I was a boy growing up. Dont ever recall seeing a tallow tree for hundreds of miles, yet the bees seemed to do just fine on clover and buttercups. Rid the tallows and watch the proliferation of native pollinator species spring forth.
C. Weevils work marginally well on salvinia, but after last week's little cool spell, they gone.
D. Subsequently, you have to have ice formation around the roots on salvinia to kill it, which we got on Caddo. But I've seen that happen before on Bistineau. It cleared it up for a couple years, but all it takes is for a few species to survive and in 2-3 years, you have a mess again.
Introducing one invasive species to combat another shows a lack of critical thought process. We have enough effective tools to control tallow; its the ability to attack broad scale that is missing at the moment.
This is a great point and should be the focus of the eradication. Returning the ecosystems that are choked with tallow back to their previous form - coastal prairie. You have to look at the potential benefits to more than one species (honey bees in this case). Tallow is devastating to coastal prairies.Micropterus said:

Also can do the same thing in forested stand, if you cut trees, tallow will come first, if you have storm that takes out bunch of trees, tallow is first to come back.Quote:
If you leave one pasture alone for five years and leave one tallow tree in it. And you were in Southeast Texas, that entire pasture is gone in five years.
Does that apply to larger trees as well? I have a 40 acre property in Matagorda county where there are several mature tallow trees (30+ feet tall) but very few younger trees, thankfully. It was my understanding that the girdling treatment was both more difficult (due to bark thickness) and less effective on mature trees. Is that your experience?rab79 said:huh, I get good results by girdling and leaving them standing for a year.iamtheglove said:

Not disagreeing with you by any means. If you kill one, there's a thousand to take its place. Its a never-ending fight. Just making the point that there are tools, especially the right herbicide applied at the right rate and via the right method can control what is there. Not trying to give the impression that it's a one and done approach - its takes years of active management, but you can hold them at bay. Now cost, well thats another factor entirely.oldord said:Micropterus said:

Brother, you must not have fought tallow trees much.
Unless you have time and money and lots of resources to throw at it. It's a never ending battle.
If you leave one pasture alone for five years and leave one tallow tree in it. And you were in Southeast Texas, that entire pasture is gone in five years.
