Our History
In 1972, Melvin Weaver was working for a local company in Lancaster selling smoked meats and cheeses. About this time, Mel had an opportunity to become a distributor for the Conklin Company—manufacturer of the surfactant, Wex. Mel began selling Wex to ag customers. These customers enquired about chemicals often purchased in conjunction with Wex. Mel found a source for these products, and the foundation for what would become Melvin Weaver Spray Materials was in place.
In 1975, Mel resigned his position selling meats and cheeses and went full-time into ag sales. He started out using a 53-foot trailer as his warehouse. When this storage space got full, Mel added a second trailer, and then eventually a third.

In 1977, Melvin Weaver Spray Materials moved to Leabrook Rd, Lancaster, PA. Mel built a 36’ x 60’ warehouse and started working from his new location. For the first few years, Mel advertised in a local farming newspaper. As the business grew, he relied only on word-of-mouth advertisement. The company’s retail side was conducted on a cash and carry policy—this transactional policy is still in effect today.
Mel did everything himself for the first few years—the purchasing, product sales, pulling orders, deliveries, and accounting. The business grew, and he hired his first employee in 1980. Over the years, growth continued, and he added additional employees.

Mel’s faith in God was the foundation of his business and his relationships with clients. He built trust with his customers. Many of these relationships were built over the phone with growers from all over the Northeast region.
Mel and his wife Norma raised their six children—Wes, Kev, Dwane, Joanne, Sharon, and Linford at the Leabrook Road location. Many family members were involved in helping with the business.
After Dwane graduated from school, he worked full-time as Mel’s right-hand man. His responsibilities included purchasing, pricing, and general management. When Linford finished school, he started off with split roles between the warehouse and office. And in a few years graduated to full-time office responsibilities.

To recognize the company’s growing family involvement, Mel changed the company name to Melvin Weaver & Sons in 2000. Then, in 2010, Dwane and Linford became partners in the company. In 2011, they developed and added the PowerAG line of micronutrients and adjuvants to Melvin Weaver & Sons. In 2020, Dwane and Linford bought the remaining shares of the company from Mel.
In 2021, Dwane passed away after fighting cancer for 3 years. His legacy, leadership, and contribution to our business will never be forgotten. All of us, including customers and sales reps, will miss his humor and engaging personality. Through the relationships that he built, Dwane left an impact on peoples’ lives that will always be remembered.
God has blessed us so much over the years. Our goal is to continue the faith and trust that Mel established when he founded the company. We are thankful for exceptional customers and key, dedicated employees who have helped us build a successful business.
