Evaluation of Chemical Agents for the Control of <i>Phytophthora ramorum</i> and Other Species of <i>Phytophthora</i> on Nursery Crops

Fig. 3. Lesion development on detached rhododendron leaves inoculated with P. ramorum N10A sporangia after foliar application of chemical agents. Complete product tradenames are listed in Table 5. Mean lesion areas for each chemical treatment are based on 4 inoculated spots per leaf; 8 replicate leaves from two combined trials (± SEM). Columns with the same letter designator are not signficantly different at P = 0.05.
