Efficacy of carbofuran and isofenphos against the sorghum shoot fly, Atherigona soccata (Rond.), in different soil types

The effectiveness of seed treatments with carbofuran and isofenphos and application of granular carbofuran against Atherigona soccata Rond. on sorghum plants grown in pots containing different types of soil from Maharashtra and Madhya Pradesh, India, was studied in the laboratory. On the basis of the percentage of deadhearts 21 days after germination, carbofuran was more effective than isofenphos. The effectiveness of treatments was reduced most by high soil pH and was also affected by cation exchange capacity, amount of organic matter and phosphorus and potash contents. Differences in the effectiveness of carbofuran as compared with isofenphos were observed between the different soil types
