Effects of different control methods on the reproduction of Meloidogyne incognita on green bean, 60 days after inoculation (greenhouse 25 ± °C).
| Treatment | No. of egg masses/root system | No. of eggs/root system | Egg mass index (EMI) (0–5) | Reproduction factor (Rf) |
|---|---|---|---|---|
| Non-infected and non-treated control | ||||
| M. incognita (N) | 705.0 a | 850, 838 a | 5.0 | 85.08 a |
| N+ Dazomet | 1.0 e | 99.0 d | 1.0 | 0.01 c |
| N+ Fenamiphos | 1.0 e | 208.0 d | 1.0 | 0.02 c |
| N+ Fenamiphos (seed dressing) | 19.4 d | 234.9 cd | 3.0 | 0.24 c |
| N+ Fenamiphos (seed dip) | 1.6 d | 722.0 cd | 1.2 | 0.07 c |
| N+ P. lilacinus | 263.8 c | 322.540 b | 5.0 | 32.2 b |
| N+ Soil solarization | 1.0 e | 143.0 d | 1.0 | 0.01 c |
| N+ Glomus sp. | 418.8 b | 372.638 b | 5.0 | 37.2 b |
| N+ Urea (46%) | 27.0 d | 5.918 c | 3.4 | 0.60 c |
Values are means of five replicates.
Means within the same column that are followed by the same letter(s) are not significantly different according to Fisher’s Protected LSD (P ⩽ 0.05).
Egg mass index (EMI): 0 = none, 1 = 1–2, 2 = 3–10, 3 = 11–30, 4 = 31–100, and 5 = more than 100 egg masses/root system.
Reproduction factor (Rf) = final nematode population (Pf)/initial inoculum (Pi).
