231. Conclusions The results published here should not be interpreted as a final assess· mant of the chemicals involved in the tests since the balance of environmental influences are extremely important in dete~ning the value of many herbicides. Bither plus or minus minor to major variations might be expected from trials conducted under other conditions. Therefore, tests conducted over a period of years are necessary to eVAluate the potential of each product.
