The thiram was used at the same rates as the insecticidal chemicals, which are much less than the usual recommended fungicidal doses. Koga II wheat was sown on April 28 and sampled 6 and 9 weeks later. Treatment effects were similar on both occasions, so only the results at the second samphng are given (Table 2).
