We don't really use the term 'late blight' over here in Belgium, we had ph.infestans in our tomatoes from the end of May, so what's late? I grew about 70 varieties, Legend, Phytoresista, Bajawa and others , all were supposed to have a very good resistance against the late blight,I got two ripe tomatoes from Phytoresista, all the other ones were killed, except one variety:tomatito de jalapa, but the tomatoes are very small. This is a variety carrying genes of other botanical tomatoes, they have a bigger resistance. Even in the greenhouse my tomatoes are affected by now, almost out-produced and very sick. The biggest factor is humidity, we had lots of rain, little sunshine to dry up the plants,
