“…Crop rotation with non-hosts has generally been ineffective in other studies in terms of reducing the density of microsclerotia of V. dahliae (10,15). In this study, crop rotation appeared to be a very effective means of reducing potential damage caused by Verticillium wilt, and microsclerotia buildup was <10% of that in CC.…”

Wheeler, T. A., Bordovsky, J. P., Keeling, J. W., Mullinix, B. G., Jr., and Woodward, J. E. 2012. Effects of crop rotation, cultivar, and irrigation and nitrogen rate on Verticillium wilt in cotton. Plant Dis. 96:985-989.A field experiment was conducted under center-pivot irrigation in four wedges, with one wedge in continuous cotton (CC) and three wedges in a rotation (ROT) with 2 years cotton and 1 year in sorghum. Three irrigation rates (base = l.OB, 1.5B, and 0.5B) were applied during 2007 to 2009 on a susceptible (ST) and partially resistant (PR) cultivar. Nitrogen applied during the season was proportional to irrigation rate. In the ROT wedges, 0.5B, l.OB, and 1.5B irrigation and nitrogen rates averaged 1, 3, and 9% incidence of wilt, respectively. Disease incidence in the CC wedge averaged 6, 18, and 34% wilt incidence for 0.5B, 1 .OB, and 1.5B irrigation and nitrogen rates. In the ROT wedges, the ST cultivar returned $143/ha more than the PR cultivars at the 0.5B

“…The latter authors observed an increase of the MS population over more than 1 year after mixing the soil with colonized ground potato stems. Also Huisman & Ashworth (1976) and Joaquim et at, (1988) found a sharp increase in MS population in the second year after growth of a susceptible crop, regardless of whether the next crop was a susceptible host or was not susceptible. The apparent increase in the year after incorporation may be explained by the disaggregation of plant debris containing MS.…”

Microsclerotia of Verticillium dahliae are produced in large numbers on senescing parts of host plants and remain viable in the soil for many years. Changes in the population density, i.e. density of microsclerotia, in the soil were measured in micro‐plots using two isolates of V. dahtiae, specific to either field bean or potato, several crop sequences comprising potato, field beans and barley, and either the removal of aerial debris of the crops or incorporation into soil. Potato was more susceptible to the potato isolate and field bean more susceptible to the field bean isolate. Removal of debris of potato and field bean reduced numbers of microsclerotia in the soil in the subsequent years, but removal of barley straw had no effect. Initially non‐infested control micro‐plots became infested, probably by the growth of potato roots into the naturally infested subsoil. The rate of increase of the microsclerotial population in the non‐infested control micro‐plots was larger than in the initially infested treatments, because more colonized debris was produced. It is concluded that removal of aerial debris of host crops is important to reduce the soil population of V. dahtiae.

“…On the other hand, crop sequences, intercrops and their rotations have long been recognized as effective long-term management strategies against soil borne pathogens (Curl et al, 1963;Huisman and Ashworth 1976;Kollmorgen, 1974;Shipton, 1977). There have been few multi-seasonal field experiments that study the effects of cropping system rotations on soil borne diseases (Natarajan et al, 1985), and no information from long-term studies in dryland cropping systems that assesses disease build-up and its effects on crop yields.…”

In many parts of India intensive cultivation of safflower on Vertisols appears to have aggravated the problem of Fusarium wilt in safflower due to the soil borne fungus, Fusarium 2 oxysporum Schlecht f. sp. carthami Klisiwiez and Houstan (FOC). In a long-term field experiment at Patancheru, India, we evaluated four diverse dryland cropping systems that each included safflower for their effectiveness in controlling Fusarium wilt in safflower. Sorghum (rainy season crop) and safflower (post-rainy season crop) were grown every alternate year as a two-year rotation with: (1) sorghum intercropped with pigeonpea (S/PP-S+SF); (2) cowpea intercropped with pigeonpea (C/PP-S+SF); (3) sorghum followed by chickpea (S+CP-S+SF); (4) sorghum followed by safflower (S+SF-S+SF). Continuous sorghum and safflower (S+SF-S+SF) had higher Fusarium wilt incidence of fully wilted safflower plants (31%) and a larger build-up of fusarium propagules (1728 cfu g -1 of soil) than other cropping systems. The inclusion of a legume such as chickpea in the rotation (S+CP-S+SF) reduced wilt incidence (7% fully wilted plants) and the level of inoculum in the soil to about 800 cfu g -1 . There was a significant increase in safflower seed yield and biomass yield (883 and 1733 kg ha -1 , respectively) in the S+CP-S+SF rotation compared with the S+SF-S+SF rotation (605 and 1323 kg ha -1 , respectively). Nitrogen application at rates of 0 to 120 kg N ha -1 had no effect on wilt incidence in safflower, but increased seed and biomass yield significantly. Intercrop rotations (S/PP-S+SF and C/PP-S+SF) were less effective to manage the Fusarium wilt. The Area Under Disease Progress Curve (AUDPC) was almost ten times higher in the S+SF-S+SF rotation (2842) compared with the S+CP-S+SF rotation (297). Wilt progress throughout the season in all four systems was linear, with significant differences in intercepts and rates of disease progress among cropping systems; the rate of disease progress was significantly greater in the S+SF-S+SF rotation compared with the other three systems, which were similar. There was also a strong linear relationship between wilt incidence and the number of Fusarium propagules in the soil; regressions had the same slope but different intercepts in each system. There was no relationship between wilt incidence and seed yield; nitrogen had the largest effect on yields.A break from safflower cultivation for one year in the post-rainy season by growing chickpea 3 as a sequential crop after sorghum, or as an intercrop with pigeonpea and sorghum, combined with higher rates of nitrogen application to safflower appears to be an effective strategy for reducing Fusarium populations and sustaining safflower yield. A long-term cropping systems study evaluated effective management option for wilt in safflower Safflower yield was higher in S+SF system following S+CP system in rotation Wilt incidence, build-up of propagules was significantly different among cropping systems Safflower yield was not significantly affected by wilt, but high...
