Field Studies on Vegetables

Beets, Broccoli, Brussels Sprouts, Cabbage, Carrot, Cauliflower, Celery, Garlic, Leek, Lettuce, Onion, Parsley, Pea, Potato, Radish, Spinach and Turnip.

These crops are prone to root diseases. Pythium, phytophthora, rhizoctonia are common root diseases in these crops. Terreplenish® is effective when soil applied before or at transplanting using 1-2 gallons per acre using enough carrier (water) to adequately disperse. Most of these crops respond well to soil application of Terreplenish® and generally do not have a favorable leaf surface and configuration for foliar application to be effective.

Potatoes are an exception and have performed well using foliar application of Terreplenish® pre-bloom. Soil applied Terreplenish® will enhance phosphorous availability in these crops and will reflect improved plant health from disease suppression. Fall planted garlic will over-winter better with 1-2 gallons of soil applied Terreplenish® prior to planting.


Bean, Cucumber, Eggplant, Lima Bean, Muskmelon, Pepper, Squash, Sweet Corn, Sweet Potato, Tomato and Watermelon.

This group of plants respond well to multiple application of Terreplenish® both soil and foliar applied. These plants are susceptible to soilborne and air-borne pathogens, insect feeding, root disease and disappointing fruit sets in less than favorable conditions.

Vine crops should be treated pre-bloom with Terreplenish® foliar to control powdery mildew, fusarium and septoria. Soil-applied Terreplenish® will help with these diseases but this group of plants are susceptible on many forms of disease vectors from cucumber beetles to field visitors. Experimentation and observation will be key for your specific operation as conditions are extremely variable.

This group of plants generally mature faster and more uniform with the use of Terreplenish®. Injection in the drip lines is a very effective method to apply Terreplenish® in this group. Adequate dilutions must be insured with overhead irrigation or other surface application.
