Recent Emphasis and Accomplishments:
Farmers in Wharton, Jackson and Matagorda Counties grow a diverse mixture of crops. Annual acreages of crops grown average as follows: corn 170,000, grain sorghum 101,000, rice 84,000, cotton 70,000, soybeans 24,000 and wheat 8,000. The ten-year average value of corn, cotton and grain sorghum in the three county area are: corn $32 million, grain sorghum $21 million and cotton $39 million (NASS 2011).
The IPM Program addresses pest and production issues identified by growers in these crops. In addition evaluates the use and timing of newly available technologies to help growers fit these into their production systems. Nine growers responded to a survey in 2010, providing information about the value of the IPM program to them in their farming operation. Fifty-six percent of the respondents said the program reduced their economic risk, 75% said the program helped them reduce production costs, 100% said the program helped them make pest management decisions, and 100% said adoption of new IPM practices had allowed them to reduce chemical use on their farms by an average of 17%. Seventy-five percent said the program helped them improve crop yields and quality. Growers said the value of the program to them was (average of the nine respondents): cotton $38.60/ac, grain sorghum $20.25/ac, corn $12.00/ac, rice $15.00/ac, soybeans $11.60/ac and wheat $3.00/ac. If the responses of the survey accurately reflect the value of the program to all crop producers in the three county area, the value of the program to corn, cotton and grain sorghum producers alone is in excess on $6.7 million per year. The grower survey also suggests that Mr. Crumley’s IPM program has aided in achieving significant reductions in pesticide use and associated environmental improvements have occurred.
