Abstract:
Broomrapes are parasitic weeds that cause severe damage to field crops. A regional survey was conducted to collect the history of 97 tomato fields to investigate the major factors that affect infection by broomrape over a two year period. In addition, broomrape infection levels were intensively mapped (40 samples/ha) in 29 tomato fields. Data from the intensively mapped fields were interpolated to characterize the spatial patterns of infection, and to postulate relationships with field history. Chi-tests based on the regional data showed that history of broomrape infection and of a tomato crop in the rotation significantly increased the risk of infection. The interpolated maps of broomrape infection pattern revealed four major spatial patterns: directional, elongated and small clusters and random pattern. Spatial analysis indicated that the proximity of infected plots was a main contributor to the incidence of infection. In plots with low and medium infection severity or with no infection record, infection level decreased with increasing distance from a neighboring infected plot, which could indicate that infected neighboring plots may serve as the initial infection sources for relatively new plots. The in-field variability explained by the proximity to infected plots may optimize sampling patterns for better estimation of the infection level. It would also enable a site-specific control strategy for alleviating broomrape damage and seed dispersal.
