Figure 1. Dose–responses curves of branched broomrape and Egyptian broomrape seed germination in response to doses of three different ammonium products under three exposure durations of 10 minutes, one hour, and 24 hours. A three-parameter logistic model (Eq.1) was fitted to germination data. Lines are fitted values, and solid circles indicate observed germination averaged across two experimental runs with three replicates each (i.e., n =6). Error bars indicate 95% confidence intervals.

California is the largest producer of processing tomato in the US (Winans et al. 2020). However, the profitability of the tomato industry in California is seriously threatened due to the presence of the parasitic weed branched and Egyptian broomrape (https://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=50241). These weeds can severely damage the host reducing the aerial biomass and leaf chlorophyll content (Mauromicale et al. 2008) with yield losses of up to 80% (Eizenberg and Goldwasser 2018).
Broomrape produces hundreds of thousands of tiny seeds (0.2 – 0.4 mm), which can be transported easily by humans, water, wind, and animals (Eizenberg et...
