General Information


ProAct stimulates the natural growth and defense systems of crops, enhancing overall plant health. Healthier plants exhibit increased plant stamina and vigor, leading to one or more of the following benefits: suppression of nematode egg production, increased marketable yield, and enhanced quality.

ProAct is a tool for use in Integrated Crop Management (ICM). Product efficacy is based on its ability to activate the plant’s own internal defense and growth mechanisms. ProAct works best when used in conjunction with good crop management practices.



ProAct can be used to suppress nematode egg production while improving plant and root growth. ProAct offers a different mode of action for nematode suppression. Use of a labeled preplant application of a soil fumigant, contact nematicide, or nematicidal seed treatment is typically needed for nematode suppression in most crops. Apply ProAct for supplemental suppression of nematode egg production.


Use ProAct to increase plant health and vigor and to enhance crop quality and marketable production.


Use ProAct for field production of all crops listed on the label.


Use spray volume adequate to obtain coverage without runoff. Uniform or full leaf coverage is helpful but is not required.


ProAct can be applied up to the day of harvest.



Use ProAct on the same day it is mixed with water. Carefully reseal opened packages to minimize exposure to air and moisture. Use opened packages within 3 weeks.


Use in mixtures: ProAct is believed to be compatible with most other labeled pesticides, such as post-emergence herbicides, insecticides, acaricides, and fungicides, as well as most foliar nutritional products. To determine the physical compatibility of this product with other products, use a jar test. Using a quart jar, add the proportionate amounts of the products to approximately one quart of water with agitation. Add dry flowables first, then flowables, and then emulsifiable concentrates last. After thorough mixing, allow this mixture to stand for 5 minutes. If the combination remains mixed or can be readily remixed, it is physically compatible. Once compatibility has been proven, use the same procedure for adding products to the spray tank. Do not mix this product with any other product containing a label prohibition against such mixing. When tank-mixing ProAct with any other approved pesticide, always read and follow all use directions, restrictions, and precautions of both ProAct and the tank mix partner(s). The resulting tank mix must be used in accordance with the most restrictive label limitations and precautions. Do not exceed label dosage rates.

Precautions: Do not use ProAct in tank mixes or water below pH 5 or above pH 10. Do not mix this product with pyrophosphates, phosphoric acid, or other strong oxidizers.

Surfactants: Use only non-ionic adjuvants approved for use on growing crops.

Glyphosate Herbicides: When tank mixing ProAct with glyphosate for application on crops designated Roundup Ready, only use formulations of glyphosate herbicide that are fully labeled for use on Roundup Ready crops. Never spray this mixture on crops that are not designated Roundup Ready as severe injury or death of the crop can occur. Some glyphosate formulations allow for the addition of surfactants. Please refer to the surfactant recommendations from the manufacturer.


If one ounce of ProAct is diluted in more than 35 gallons of chlorinated water (e.g., municipal water), add a labeled water treatment product to remove excess chlorine. Consult your Plant Health Care representative if you need further directions on water treatment.


Crop maturing can infrequently differ in crops treated with ProAct. User must monitor crop for maturity and harvest accordingly.


Do not apply during rain. Reapplication is not necessary if the spray has dried before rain begins.


Plants must be actively growing at the time of foliar applications. Applications made to plants that are stressed by extreme heat, cold, moisture, or nutrient deficiency can be less effective.


Avoiding spray drift at the application site is the responsibility of the applicator. The interactions of many equipment and weather-related factors determine the potential for spray drift. The applicator and the grower are responsible for considering these factors when making decisions.

Limitations, Restrictions, and Exceptions


Use ProAct following a preplant application of soil fumigant, contact nematicide, or nematicidal seed treatment, if available. Make first foliar application of ProAct at 2 - 3 weeks after plant emergence. Re-apply as recommended in Table 2 at the label.


Use ProAct following a preplant application of soil fumigant, contact nematicide, or nematicidal seed treatment, if available. Make first application of ProAct after plants break dormancy and begin root growth. Re-apply as recommended in Table 2 at the label.


Apply after new growth commences. Repeat at 28-35 day intervals as needed.
