    Monterey Insect control

    By Darrell on 07/24/2016

    I was recommended to this product by Pro-cure Nursery. It was the end of May and I was told, that to be effective it should be applied in March, before sap was rising, to be effective. I went ahead and applied to 5 mature pecan trees. In mid June the worms hit heavy. I watered heavy with my springlers and could the see leaves green up and grow darker. Leaving me to believe I was pulling the sap to all of the tree. The worms were very active for about 3 weeks, Since July ! I have not found a single live worm. They have completely dried up. (They look like sand burrs in a wad) I will for sure treat all trees in March nest year

    Monterey

    By Drucilla on 01/19/2015

    Verified Purchase

    It was easy to mix and use. Not sure how the end results will pan out because it is a systemic application and it takes time for the plants to take in the product and the insects to die. I'm hopeful that it will work and I will continue to purchase this

    Didn't fix my Mealy Bug Problem

    By Rusty on 08/09/2017

    It didn't work on my Problem !!! BUT I was using it on Dipladenia & Mandevilla and the Mealy bug were well ahead of me. I had used Lady bugs. They got the Aphids but maybe I waited too Long to use the Juice. I used half a bottle in 2 gallons of Mix on 6 POTS.

    Too Early To Tell Yet

    By Ryan on 02/23/2018

    I just applied this to the base of my crepe myrtle tree. I won't know until mid summer if it kept the aphids away.

Q
For Monterey Insect Control, must the ground be bare or can this be used on grassy soil

I was told that this would only work on bare soil, otherwise just the plants would absorb the product and not the tree

A
Grasses or other plants could absorb some of the product but if you use a higher volume of water it will really help get the product down to the roots of the tree.
