Bush Beans Contender: Identification of Plant Disease
Bean
South Africa
I have sown (direct) Contender bush beans on 31 October, with germination starting around 6 November. The plants are now on average 15cm high. I have done preventative spraying for red spider mite on 10 Nov - applying Makhro Seizer 100 and Makhro SK Eco Oil. The application was done early morning - no direct sunlight. I, however, noticed some leaves on a few plant looking sickly with "bruised"-like areas that appeared like damaged plant cells. To me, this looks like an early form of blight and I have this morning sprayed Efekto Virikop.
Can anyone perhaps help identify what it is and the cause, so that I can take corrective action.
I have 300 plants in an area of 14sqm (14m x 1m) planted in three parallel rows. Plants 10-15cm apart and rows 30cm apart.
UPDATE<\b>
Since the last posting, the situation is worsened and most of the plants now show similar damage to the leaves. I have added new photos to show this. The damage appears on the first growth of leaves - the second set is now appearing and I would like to stop this spreading to this new growth.
