Product Overview

Monterey Complete Disease Control is a bactericide and biofungicide rolled into one formula for early diagnosis of bacterial and fungal diseases in plants that may affect leaves, roots, stems or be transferred internally without obvious symptoms. This product can be used as a soil drench to plant roots or as a spray to fruit and foliage. When applied as a soil drench, this naturally materializing bacterium goes directly to the roots of the plants, where it will set itself and grow. This colonization inhibits the establishment of bacteria and fungi carrying diseases. When applied as a foliar spray, the bacterium in this formula will overpower any pathogenic spores present. The application through spray is recommended for those diseases affecting fruits, leaves, and flowers or even anything above ground. While application through drench is preferred for diseases affecting tubers, roots, or any other part of the plant that comes in direct contact with the soil. It is highly recommended to treat plants at the early signs of diseases or even before the disease develops. This OMRI listed formulation can be applied up to the day of harvest.

Foliar Spray:

  • Use RTU or mix 1 tsp. of concentrate with 1 gallon of water. Shake well.
  • Spray leaves, stems and new shoots to runoff, providing complete coverage of the entire plant.
  • Repeat at weekly intervals or as needed (typically every 7 to 10 days).
  • In conditions favorable to rapid disease development, such as high humidity, excessive rain or other conditions of extreme moisture, increase the mixing rate to 1 tbsp. per gallon and shorten the spray interval to every 3 to 7 days.
  • Allow spray to dry at least 4 hours before watering if foliage will also be watered.

Soil Drench:

  • Mix 1 tsp. per gallon of water and apply to the soil using one of the following methods:
  • For potted plants (indoors or outdoors), use a watering can or tank-fed watering wand to apply sufficient water to wet the entire root mass. Or use a hand-pump or other sprayer to spray the mixture on the surface and then immediately water it into the roots.
  • Drench the roots of transplants with approximately 4 fl. oz. of the mixture immediately before transplanting. Allow to soak into the root ball when transplanting.
  • For outdoor-grown plants, use a watering can or sprayer to drench the soil in the planting furrow or transplant hole immediately before planting or transplanting.
  • Apply in the first watering after planting or transplanting, either by mixing directly into the water or by spraying onto the soil surface and watering it in.

For Lawns/Grassy Areas:

  • Mix 1 tsp. of water per gallon of water and apply as a fine spray to the surface area. Typically, 2 to 5 gals of spray may be required per 1,000 sq. ft. of lawn. Water in the mixture immediately after application.

    Fabulous Product!

    By Kathleen on 07/18/2017

    I found this highly recommended product at the best price on this site. We had a small maple tree that had brown spots on all of its leaves. The spots did not brush off, so I was concerned that something had infected the soil and then tree. After one spray and soil application, new growth appeared - fresh and green with no spots. I've poured one more gallon of treatment solution around the base, to be sure. Seems to be just what we needed!

    Not Totally Complete

    By Dennis on 04/24/2020

    I struggled with reoccurring fire-blight and fungal diseases on my fruit trees. After using agricultural streptomycin on the dormant trees as I did in previous years to kill the fire-blight I used Monterey Complete Disease Control at budding time and every two weeks thereafter. The fire-blight was greatly reduced to only two small infections. After removal of the two fire-blight infections I continued with the Monterey spray with no reoccurrence of the fire-blight. However, eventually fungal disease resurfaced in the trees so I had to use other fungicides to control it. In the past years I had used other fungicides with moderate but not complete success. I found alternating a fungicide and Monterey sprays did the trick. The fruit trees are disease free.

    Seems to be keeping blight and fungal diseases at bay

    By Dennis on 05/03/2019

    In the past I used many products to keep my fruit trees (apple, pear, plum, peach, cherry) free of bacterial and fungal diseases with moderate success. This year (as I do each year) I sprayed with Agri-mycin antibiotic and a fungicide to knock down bacterial and fungal diseases before blossom. Beginning at blossom time and repeating about every week since then I used the Monterey Complete Disease Control. My trees look very disease free and much better than in previous years. My hope is that this can continue throughout the fruit growing season. I am at this point pleased with this product.

    Not sure if has ever worked

    By Jim on 09/09/2022

    I submitted a review a couple months ago, but it seems that domyown never posted it, or pulled it. I bought the product, and have used almost the entire bottle over the past year or so. (As a soil drench.) Many of my indoor plants (mostly geraniums) have gotten root rot and black leg nonetheless. Perhaps I over water a bit too much. But this product is supposed to PROTECT the plants. At least that's what Monterey tells me. They also tell me It won't cure a sick plant. I can confirm that. Despite my doubts about the efficacy of the product I may buy more. I don't want my plants getting any sicker.

    I've seen no evidence it works.

    By Jim on 08/01/2022

    I bought this product to protect the plants I have inside my home, and have used it for close to two years. I've seen no evidence it is effective against root rot or black leg. I've had a half dozen plants get ill and die from these two diseases, and I am very careful to use new potting soil and disinfect my pots and tools. I also SUSPECT, but do not know for certain that it inhibits root formation as none of my cuttings that I watered with the product seem to grow roots.

What's the best replacement for Serenade, the discontinued fungicide?

Serenade was a Bayer OMRI listed fungicide using Bacillus subtilis. It was recommended by my gardener for treating fungal issues in our stonefruits, bramble & bush berries, but it's been discontinued. Which would be a better replacement for that use, the Monterey or Cease by BioWorks? Thanks!


Monterey Complete Disease Control would be the best alternative product for Serenade Garden Disease Control Concentrate
