Amma Simon presents some work about aphids and fusarium on wheat; R. padi goes on leaves/stems, S. avenae on heads, which also can get Fusarium. Therefore, S.a. avoids Fusarium-infected wheat but R.p. does not, and can benefit from infection!

🚨 First Look! My latest peer-reviewed co-authorship is now online in Phytopathology Journal 🧬🌾

📰 Fusarium avenaceum isolates from pea, wheat, & lentil were tested on these three host crops. Pea-derived isolates were the most "aggressive," which motivated our conclusion that inclusion of pea in a crop rotation can increase the incidence & severity of head blight in wheat.

I'd consider myself a fairly well versed gardener. I worked in landscaping and landscape design for years, but I'm stumped when it comes to my current red currant issue. (So much pun.) I have two that were planted in late Feb/ late March.

Currant 1 flourished, put on lots of new growth and appeared to be doing well.

Currant 2 went in a little later due to logistics but has grown well.

Currant 2 definitely has leafhoppers, but no signs of damage and is now double the size of Currant 1 and thriving.

Currant 1 is an entirely different story. We had a windstorm and some of the new growth got whipped around and snapped. I trimmed the broken growth with clean secateurs (alcohol and all). It has gone from thriving to barely surviving since then. I can't find any pests and the only sign of any is a couple of leaves munched by either mason or leafcutter bees and maybe earwigs. The leaves grow and then it's like something has lopped them off halfway down the stem of the leaf. I'm starting to notice varigated mottling on some new growth and distortion of new leaves. Is this fungal? Viral? I've never seen it before. Both are partial shade with new potting soil. Zone 8.

Thoughts? We don't live in an area affected by pine blister if that helps.
