The cool summer of 1993 damaged the rice crop nation-wide. Furthermore rice blast was found to be widespread in Ibaraki, Tochigi and Saitama Prefectures. The race of rice blast fungus isolated in Ibaraki, Tochigi and Saitama Prefectures were 001, 003, 007, 033 and 037. In 1988 the major race was 003 in these prefectures, but by 1993 this had been replaced by 007. Because of the increase of race 007 the area planted with Kinuhikari and Asanohikari varieties of rice, which have a resistance gene
Pi-i, was increased.

Leaf disc tests taken over a period of 3 years on 324 isolates of cucumber powdery mildew fungus,
Sphaerotheca fuliginea (Schlechtendahl: Fries) Pollacci, revealed that a resistant strain to DMIs was distributed widely in the Kanto-Tosan District. The degree of resistance to triflumizole was always less than to triadimefon and fenarimol, although cross resistance among the DMIs was clearly shown. In general field performance of triflumizole was considered to be still good, because triflumizole was the most frequently used fungicide among DMIs registered for cucumber. From 1991 to 1992, the unimodal sensitivity distribution for each DMI tested gradually shifted towards lower sensitivity. However from 1992 to 1993 the reverse was true: sensitivities to DMIs were observed to increase. This phenomenon corresponded to a decline in the number of DMI applications to cucumber in the district. These results indicate that restricted use of DMIs may prevent a further decline in sensitivity of
S. fuliginea.

The performance of DMIs on cucumber powdery mildew,
Sphaerotheca fuliginea, was found to be acceptable for a period of three years following the introduction of these fungicides. However, sencitivity level of the fungus gradually decreased during this period, especially more than one DMIs applications was made in one month period.

Sphaerotheca fuliginea from Saitama Prefecture showed high resistances to DMIs. However, the degree of resistance to triflumizole was less than to triadimefon and fenarimol. When DMI use was suspended, the a sensitivity of the fungus seemed to increase.

Three applications of triflumizole followed by two of quinomethionate showed excellent control of cucumber powdery mildew in a plastic house. Previously the performance of triadimefon in the plastic house was poor because of resistance and so DMIs were not used. Sensitivity to triadimefon seemed to be regained more than four years after the suspension of DMI use. On the other hand, sensitivity to triflumizole has decreased little over three successive years of trial use.

In 1991, a resistant strain of
Sphaerotheca was found for the first time in Yamanashi Prefecture. There were some cases where the suspension of DMI applications caused increased sensitivity of the fungus, but non-DMI fungicides showed good performance to powdery mildew in the cucumber field in which DMi resistance had occurred.

Decreased sensitivity in
Sphaerotheca fuliginea to DMIs was found in most of the cucumber fields investigated in Nagano Prefecture. The degree of resistance to triadimefon and fenarimol was rather high, and many isolates were more than 100 times less sensitive compared with the reference sensitive strain. A reduced number of DMI applications marginally increased sensitivity.
