Thrips on lettuce :(
Comments (1)OMG THANK YOU! I have been trying for two weeks to identify these things that are in my garden, when you mentioned 'thrips' I did a search on google images and sure enough, that's what I have and they have been raising hell in my garden. I don't know how to get rid of them, but now that I know what they are I'm going to start searching =)...See Morespots on photinia...help!
Comments (5)The fungicide for photinia leaf spot serves a protective purpose. In other words, it protects new growth from becoming infested. I'd say that the nurseryman you spoke with was being rather dramatic when he said the trees would die in several years. Here in the PNW, photinia are affected every year. And I would suspect the NW infections are more extensive thn those in your region, simply because our climate is more wet than yours. Our photinia trees/shrubs live many years in spite of the problem, although I must admit that they can look rather nasty if in a site favorable to infetion.. In OR, the suggested sprays for homeowner use are any of these: Daconil; Hi-Yield Vegetable, Flower and Ornamental Fungicide; Immunox; Systemic Fungicide (ferti-lome); or Rose Pride Funginex. Because the trees are so important to you, consider hiring a certified arborist to spray because they have equipment you don't. Look for a certified arborist in the Yellow Pages under the heading of Trees or Tree care. Companies that have a certified arborist say so in their ad. The appropriate time to spray is in early spring when the new shoots are developing. In oher words, protect new growth from becoming infected. Also useful for limiting infection are good air circulation (thinning the trees might help); keeping the leaves as dry as possible; and full sun exposure. Also remove and destroy affected leaves....See MoreRecovering from THRIPS and tomato spotted wilt
Comments (4)Well for sure bleach and rinse out the containers and like farmerdill said, look for resistant varieties. you can start to spray with the mixtures in your previous threads as a precaution to avoid thrips from starting. I also am a container gardener for the most part, and location won't make that much of a difference, I don't think. You need a clean container and fresh soil - make sure it is for containers and not soil for the garden. Sharon...See MoreDoes this Photinia have black spot?
Comments (30)Out here Extension tells us The fungus overwinters in diseased leaves and shoots. Spores are disseminated by splashing water and need 9 to 12 hours of leaf wetness to infect leaves. Bright sun reduced spore survival during dry periods. Young expanding leaves are most susceptible. https://pnwhandbooks.org/plantdisease/host-disease/photinia-leaf-spot and that the separate condition Physiological leaf spot is on photinia in western Washington https://pnwhandbooks.org/plantdisease/host-disease/photinia-physiological-leaf-spot...See Morewestes Zone 9b California SF Bay
