General Information


Shake well before using.

Apply Quali-Pro TM 4.5 with ground or aerial equipment using sufficient volume of spray to provide thorough coverage. Add required amount of Quali-Pro TM 4.5 to partially filled tank agitated by mechanical or hydraulic means and then add remaining required amount of water. Continuous agitation is required to keep the material in suspension. Do not tank mix with highly alkaline pesticides such as Bordeaux mixture or lime sulfur. No claim of compatibility with other pesticides is implied. Use the higher rate under conditions of severe disease pressure. Also see local State Extension Service instructions for application schedules.

Use the fl oz/acre rate for concentrate sprayers. Use the fl oz/100 gal rate for dilute ground application.

For aerial applications, use a minimum of 5 gal/acre for row crops; use a minimum of 10 gal/acre for tree crops. For ground applications, use a minimum of 20 gal/acre for row crops and 30 gal/acre for tree crops. Higher spray volume will result in better coverage and better disease control.

When an adjuvant is to be used with this product, Makhteshim Agan of North America, Inc. suggests the use of a Chemical Producers and Distributors Association certified adjuvant.


To avoid the development of tolerant or resistant strains of fungi, tank mix Quali-Pro TM 4.5 with a fungicide of different chemistry, and/or alternate a fungicide of different chemistry with Quali-Pro TM 4.5 at each application. DO NOT USE PRODUCTS CONTAINING THIABENDAZOLE OR OTHER PRODUCTS CONTAINING THIOPHANATE METHYL IN COMBINATION OR IN ROTATION WITH QUALI-PRO TM 4.5. If after using Quali-Pro TM 4.5 as directed and the treatment is not effective, a tolerant or resistant strain of fungi may be present. Discontinue the use of Quali-Pro TM 4.5 for at least one season. Do not use products containing thiabendazole as substitutes for Quali-Pro TM 4.5, as they are of similar chemistry and will contribute to the development of resistance. As long as these precautions are followed, Quali-Pro TM 4.5 can be useful for disease control even if resistant strains are present.
