52 Diseases of Truck Crops 



Soil-Infesting Insects 



Soils infested with insect pests are as sick as when 

 infested with eel worm or parasitic fungi. The 

 trucker, in sowing his seed, has often great difficulty 

 in obtaining a good and even stand. The frequent 

 resowings invariably result 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 (Melanotus sp.), and white grubs 

 (Phyllophaga sp.).
