Uromyces viciae-fabae, Broad bean rust 

Together with my allotment, I inherited a few crops sown by the previous tenant, one of these being broad beans (Vicia faba). As the plot had laid abandoned for a while, the plants had suffered from the period of drought we experienced earlier this summer so weren’t doing particularly well at the point I took over, but I tried to revitalise them with abundant water and fertiliser. It seemed to work, as they started flowering again and I even got to harvest one single pod, but it was already getting late in their productive season, and shortly after the first signs of broad bean rust started becoming evident, so I ended up cutting them down and disposing of them. 

This particular fungal disease affects only this species, and tends to overwinter as hardy spores in the soil, so I will avoid growing broad beans again, at least in the same raised bed. It can be controlled with fungicides during its early stages, but using resistant cultivars is the best practice, and plants are more likely to be affected towards the end of their cycle anyway.

w moim odawarskim ogródku: Bób kwitnie. Siałam nasiona, które kupiłam w Polsce. Mak wątpliwy też kwitnie. in my garden in Odawara: Broad bean blooms. I sowed seeds that I bought in Poland. Long-headed poppy also blooms. 【庭】ソラマメの花が咲いた。パンダみたいなカラーリングで愛らしい。 ポーランドで買ってきた種を蒔いた。左からディル、チャイブ、蜜源植物ミックスの種。 ナガミヒナゲシの花はきれいだけれど、増えると困るので、種ができる前に処分する。

The fate of the bean is in the hands of the fungus. By enhancing the Vicia faba's immunity against Rhizoctonia solani root rot diseases through the application of arbuscular mycorrhizal fungi and nano chitosan, the future of this legume is assured. The science of tomorrow is written in the soil.

Effect of tebuconazole on the use of reserve substances deposited in the seed of Vicia faba L. at the heterotrophic phase of development under conditions of photo- and scotomorphogenesis

The combination of external (light/dark) factor and the action of the gibberellin synthesis inhibitor tebuconazole during seed germination significantly changed the pattern of source-sink relationships in horse beans seedlings. Under the action of the tebuconazole the epicotyl, root, and seedling length in general were reduced significantly, both at light and dark. Similarly, the dry matter mass of the seedling organs was decreased. Seed reserve substances were used more intensively under conditions of scotomorphogenesis, as evidenced by the minimum cotyledons dry matter mass in this variant and higher utilization rates of reserve substances for root and epicotyl formation during germination. The retardant application led to a slowdown in the outflow of seed reserves for the formation of epicotyl and root. Under conditions of scotomorphogenesis, the rate of reserve seed starch use was higher. The gibberellin biosynthesis inhibitor tebuconazole did not affect the rate of cotyledon starch hydrolysis, indicating an internal sufficient supply by reserved forms of gibberellins. The higher sugar content in the cotyledons of scotomorphic plants, both in the control and under the action of tebuconazole, is explained by the slowing of the outflow for the needs of organogenesis — the formation of root and epicotyl structures. Quantitative changes of the nitrogen content in the cotyledons of scotomorphic and photormorphic plants during germination were much smaller than the changes of the starch content. It was no significant effect of tebuconazole on the remobilization of nitrogen-containing compounds and mineral nutrients — phosphorus and potassium deposited in the seed, on the needs of organogenesis.
