Sure. I haven’t seen this disease inthe field but my pathology traning helps.
Number one it ain’t easy to diagnose. To be 1,000% sure you need to infect a healthy plant and show it can be transmitted. Not like looking at a fungal spore sac dropping billions of powdery mildew spores. Then to be 10,000% certain you do a tissue prep, soak it in some wax or plastic, thin section it and look under an electron microscope for tiny little RNA hairpins. Seriously who is going to pay for that - commercial growers. If you look at pictures of HvLD infected plants they look normal just tiny.
Your plants didn’t display that symptom.
