NECESSITY FOR A MONTANA LAW REGARDING ADULTERATED 



INSECTICIDES. 



We ha\e had a mnnher cU" comphiints fr^nn dilTerenl parts of the 

 State, incUcating that adnlteraled or mishrandcd insecticides and 

 inngicides were on sale, and we wish to call attention lo (he harm 

 that resnlts from snch sale, in the firsi place, the farmer who buys 

 and uses snch inferior goods is defrandeil and fails lo save his crop. 

 The cost (M" the insecticides is usualK \ er\- small compared with the 

 ^a^•ing• residting fi^om their proper use. In the second ]ilace. the 

 farmer w lio unw itt ingl_\ us.s adulterated giiods. too often gains the 

 impression that no henetit results from such spraying, becomes 

 discouraged, and max feir \ears make no fu.rther effort to control the 

 ^ame pest. 



The federal law regarding adulterated and niisbranded insecti- 

 cides, known as the "Insecticide Act ^'i ujio". lakes effect January 

 ist, iQii, ;uul amiii\- pro\ides iov the protection of the country with 

 /espect lo insecticides and fungicitlcs that enter into interstate com- 

 merce. It is highly ilesirable that a state law be enacted, framed on 

 the same lines as the national law. in order that the Stale mav re- 

 V eive the further lu-oiection adored b}' pre\enling the manufacture 

 .uid distribution oi adulterated and niisbranded products within its 

 i'nes. A\'e recommend that such a law be enacted during the com- 

 ing session oi the legislaliu-e. At the present lime practically no 

 insecticitles or fungicides are manufactured in the State except for 

 home use aiul there would be no o]")position to the passage of the law. 

 \vhile there is at least a possibility that manufacturers might move 

 \u{o the Slate if there were no law lu-evenling such fraudulent prac- 

 tices.
