Membership in WPHA is broken down into five categories: fertilizer manufacturing, retail, crop protection manufacturing, formulators and associate members (providers of services to members). Since the application process consists of filling out forms for these individual areas, it is easiest to contact the WPHA office in Sacramento, Calif. You can do this by calling Judith Dickson at 916-574-9744, or e-mailing her at judithd@healthyplants.org.

We welcome and look forward to working with new members and we guarantee a rewarding and profitable relationship as we continue to maintain and improve our valuable and important industry.
