    3 of 5 stars  Monterey
    By Drucilla in Lehigh Acres, Florida 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

    5 of 5 stars  Monterey Insect control
    By Darrell in Bethany, OK 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

QWhat should I do if Monterey Once a Year Insect Control II is not controlling scales on my Jasmine?
I have scales on my jasmine and I have used Monterey once a year in the past but this year its not working.

A

If you have already applied the Monterey Once a Year, and you are still seeing scale populations, then we would recommend pairing that treatment with a topical spray to knockdown the existing insects. Ferti-Lome Triple Action with 70% Neem Oil†contains both pyrethrins and neem oil to suffocate and kill insects on leaf surfaces such as scale. Be sure to treat either in the morning or evening and to get thorough coverage of all leaf surfaces, especially the undersides of leaves.

If you are concerned about resistance to the imidacloprid because of years of use, then you could switch to a newer active ingredient, dinotefuran, which is found in Safari 20SG and Zylam.

QI have 8 crepe myrtle trees with multi-trunks. Is it reasonable that I would need 4 gallons?
trying to make sure I am measuring these multi trunk trees correctly. Some have 5+ trunks.

AWhen using Monterey Once A Year Insect Control II, you will measure the distance in inches of each tree trunk and add them together. You will then multiply this total by 0.75 to get the required number of ounces of product to apply. You will need to make sure you are using this in at least 3-5 gallons of water to ensure that the product is getting into the roots properly.
