Alternative Chemicals. Little work has been done on organochlorine alternatives. DDT and BHC are the main materials used in controlling beetle and cutworm attacks, and from experience with agricultural and horticultural crops it may not be easy to find satisfactory alternatives. While organophosphorus systemic insecticides give good control of aphids in many horticultural tree crops these materials are seldom effective, other than in a contact sense, when used on conifers. The Commission recommends malathion for controlling aphids and collembola. 6. SUMMARY AND SOME CONCLUSIONS 6.1. Summing the estimates of usage tabulated in the preceding pages gives the rounded totals shown in Table 6.1, which indicates the overall extent of use of organochlorine insecticides on outdoor crops in England and Wales in 1965-66. Glasshouse and nursery uses have not been included because the data in Table 4.2.1 can only be interpreted in ‘spray-acre’ terms. Table 6.1.
