exportation of 10,000 tons is expected at an average price of 500$000 
per metric ton. Six extraction plants are now in operation, with 
3,500 contos de reis of capital and employing about 300 workmen. 
Crilley (107) in 1937 reported that cube planters in the I qui to s 
district of Peru have decided to limit root supplies until the local 
price increases to 60 centavos per kilo, according to reports received 
in Lima. It is also said that further plantings might not be made. 
Planters claim that the American market prices do not Justify the low 
prices of 40 to 50 centavos per kilo paid to planters by cube buyers in 
Iquitos. 
An editorial in a Lima paper advocated Government intervention 
in regulating cube prices and suggested the establishment of a chemical 
laboratory in Iquitos to assist producers in ascertaining the exact 
rotenone content of their shipments. 
Crilley (108) in 1937 reported on cube exports from Peru. The 
exports of cube root from Peru increased from 254,665 kilos in 1934 to 
439,544 in 1935. In the first 10 months of 1936 exports totaled 
303,125 kilos. Planters complained during 1936 of low prices and 
exporters complained of unethical practices such as shipping root of 
mixed qualities of rotenone content, which fact may tend to influence 
foreign buyers unfavorably. It is believed that new plantings are not 
being made as rapidly as was reported to be the case last year. 
Practically all shipments are,* exported from Iquitos. Government 
intervention in regulating prices and standardizing the new industry 
was suggested. Principal buyer of Peruvian cube is the United States, 
which took 263,772 kilos of 1935 exports. 
Cube was used to an increasing extent in Peruvian production of 
cattle dips and insecticides, for the sale of which considerable 
advertising was done. At least one small factory in Lima ground the 
root for local use. The insecticide "Cubex" was reported to have been 
sold in larger volume in 1936 than previously. Some criticisms were 
heard from home users concerning the odor of domestic insecticides as 
compared with the more pleasing scent of certain imported American 
products.
