Figures & Tables

Figure 1

Reproduction of Meloidogyne enterolobii expressed as number of eggs per root system of tobacco inoculated with 1,000 freshly hatched second-stage juveniles, treated with non-fumigant nematicides, and harvested at 60 d after inoculation. Data were combined over two experiments and are means of 10 replications. Within columns, means followed by a common letter are not significantly different according to Tukey’s HSD test (P ≤ 0.05). Burkholderia refers to Burkholderia rinojensis strain A396 secondary metabolites.

Reproduction of Meloidogyne enterolobii expressed as number of second-stage juveniles per 100 cm3 of soil containing tobacco inoculated with 1,000 freshly hatched second-stage juveniles, treated with non-fumigant nematicides, and harvested at 60 d after inoculation. Data were combined over two experiments and are means of 10 replications. Within columns, means followed by a common letter are not significantly different according to Student’s t-test (P ≤ 0.05).

Dry weights of tobacco roots 60 d after inoculation with 1,000 freshly hatched second-stage juveniles of Meloidogyne enterolobii and application of non-fumigant nematicides. Data are means of 10 replications. The plant material was dried at 45°C for 2 wk. Bars with common letters are not significantly different according to Tukey’s HSD test (P ≤ 0.05).
