52 Diseases of Truck Crops 



Soil-Infesting Insects 



Soils infested with insect pests are as sick as when 

 infested with eelworm or parasitic fungi. The 

 trucker, in sowing his seed, has often great difficulty 

 in obtaining a good and even stand. The frequent 

 resowings invariably resvdt. in late crops, and this 

 means heavy money losses. Frequently the stand 

 is reduced by fifty per cent, in spite of: the many 

 resowings. The cause of this may be traced to the 

 presence in the soil of certain insect pests. Among 

 those dreaded most by the trucker and gardener are : 

 Cutworms (Agrotis sp.); (Lycophotia sp.), (Peridroma 

 sp.), wireworms {Melanotiis sp.), and white grubs 

 (JPhyllophaga sp.).
