Abstract
SUMMARY Experiments testing the effects on leafless peas of aldicarb, triazophos and a mixture of benomyl with zineb, were made on clay-with-flints soil at Rothamsted and on sandy loam at Woburn in 1977 and 1978. The crop was shown to be susceptible to a wide range of pests and pathogens including the pea and bean weevil Sitona lineatus , the migratory nematode genera Pratylenchus , Tylenchorhynchus and Tylenchus , the pea moth Cydia nigricana , the aphids Acyrihosiphon pisum and Macrosiphum euphorbiae , the bean leaf roll and pea enation mosaic viruses and the powdery mildew fungus Erysiphe polygoni . The mean yield of the four experiments when none of the treatments was applied was 3·6 t grain/ha, increased to 4·3 t/ha when all were applied. Aldicarb had the largest effect and increased mean yield at Rothamsted by 0·3 t/ha, attributed mainly to control of S. lineatus , and by 0·8 t/ha at Woburn attributed to control of S. lineatus and perhaps also to migratory nematodes, particularly Tylenchorhynchus . Triazophos and benomyl plus zineb did not individually increase yield but at Woburn when both aldicarb and triazophos were applied benomyl plus zineb increased mean yield by 0·7 t/ha. All crops lodged severely, irrespective of treatment but perhaps because of experimental conditions. We suggest that susceptibility to lodging under field-scale conditions requires further study.
