SUMMARY Spraying tomato plants infected with tomato mosaic virus (a strain of tobacco mosaic virus) and uninfected ones at weekly intervals with a 0·3% aqueous solution of urea, or this solution with 0·1% mono‐ammonium phosphate and 0·1% potassium sulphate, had little effect on the yield or quality of the fruits, although there was a slight increase in mean weight per fruit in sprayed, early‐infected plants. Steaming the soil did not affect total yield of fruits (weight) but increased fruit number by nearly 6% and also the proportion of good quality fruits. Some severe fruit‐quality disorders were prevalent only on late‐infected plants. A mild tobacco strain of mosaic virus failed to protect inoculated plants from late infection with the tomato strain of the virus.
