“…Reducing initial concentrations and increasing distribution and persistence in the soil would have an effect equivalent to the small amount of MX applied at higher concentrations. The concentration–time product (CTP) achieved determines the nematode control efficacy, and at the same CTP, the lower concentration and longer operational time are more effective in the control of plant-parasitic nematodes compared to the higher concentration and shorter operational time ( Hague and Sood, 1963 ; Hague et al, 1964 ). Thus, this application method of MX may not only reduce phytotoxicity, but also enhance efficacy in controlling RKNs.…”

This study sought to control the root-knot nematode (RKN) Meloidogyne incognita using benign organo-chemicals. Second-stage juveniles (J2) of RKN were exposed to dilutions (1.0%, 0.5%, 0.2%, and 0.1%) of acetic acid (AA), lactic acid (LA), and their mixtures (MX). The nematode bodies were disrupted severely and moderately by vacuolations in 0.5% of MX and single organic acids, respectively, suggesting toxicity of MX may be higher than AA and LA. The mortality of J2 was 100% at all concentrations of AA and MX and only at 1.0% and 0.5% of LA, which lowered slightly at 0.2% and greatly at 0.1% of LA. This suggests the nematicidal activity of MX may be mostly derived from AA together with supplementary LA toxicity. MX was applied to chili pepper plants inoculated with about 1,000 J2, for which root-knot gall formations and plant growths were examined 4 weeks after inoculation. The root gall formation was completely inhibited by 0.5% MX and standard and double concentrations of fosthiazate; and inhibited 92.9% and 57.1% by 0.2% and 0.1% MX, respectively. Shoot height, shoot weight, and root weight were not significantly (P ≤ 0.05) different among all treatments and the untreated and non-inoculated controls. All of these results suggest that the mixture of the organic acids may have a potential to be developed as an eco-friendly nematode control agent that needs to be supported by the more nematode control experiments in fields.

“…In the second experiment, satisfactory growth responses similar to those of Read (1965) were obtained at dosages of 8 oz for 50 hr and 16 oz for 26 hr but not at 4 oz for 98 hr -a dosage which controlled potato root eelworm in the first experiment. Within limits, as shown by Hague and Sood (1963), the concentration of methyl bromide can be reduced with a corresponding increase in time of application for nematode control, but where root fungi are the main source of disease it may be necessary to give higher doses. In the present experiments brown root rot was not controlled, but in recent National Agricultural Advisory Service trials methyl bromide applied by the second author gave good control of root rotting fungi at 16 oz/100 sq.…”

“…The use of methyl bromide as a soil fumigant has attracted increasing attention in recent years as it rapidly breaks down and disperses, enabling crops to be planted four days after treatment. Methyl bromide gave a commercially complete kill of potato cyst nematode in pots (Hague and Sood, 1963), and increased yield and controlled potato cyst nematode in glasshouse soils inf'ested also with the grey sterile fungus (G S F) (James and Hague, 1967). G S F is the cause of corky root rot (Preece, 1964).…”

SUMMARY Methyl‐bromide (1 lb/100 sq. ft), applied as in commercial practice, gave an increase in yield of both grafted and ungrafted tomato plants in glasshouse soils naturally‐infested with root diseases. Grafted plants greatly outyielded ungrafted plants on treated and untreated soil where phytophthora stem and root rot was present. The effect of the gas on corky root rot varied in the experiments and, on one nursery, control of the disease was not reflected by increased yield.
