Phytophthora infestans

Next, we observed that the activity of this isoPO was higher in calluses than in intact plants. Moreover, the significant activation of this isoform (pl 8.5) was shown in potato calluses infected by Phytophthora infestans (Fig. 1). 

We observed the activation of chitin-specific PO during infection with the causative agents of a number of diseases in wheat under the influence of Btpolaris soroktntana and the elicitors (Fig. 4), Septoria nodorum (Yusupova et al, 2006) and Tilletia caries (Khairullin et al., 2000) in potato infected by Phytophthora infestans (Maksimov et al., 2011), and in Aegilops umbellulata infected by Septoria nodorum (Maksimov et al, 2006).

There are more than 100 patents for plant protection by 1,2,4-oxadiazoles. For instance, the oxime ether (257) is claimed to be more effective than known compounds against Phytophthora infestans when applied protectively to tomatoes <87GEP(0)3528753>. Sprays of 5-trifluoromethyl-1,2,4-oxadiazoles, such as (258), show 90-100% protection against Erysiphe gmminis in barley <89JAP(K)63162680>. Other oxadiazoles, for example (259), show complete control of diverse weeds with no damage to rice crops <91JAP(K)02250873>.
