have been taken so frequently upon that plant, and under snch pecu- 

 liar circumstances, that they, too, may prove to be its enemies. Among 

 these latter I would mention several of the Eleodes, one Gollops, and 

 several Diptera. 



REMEDIES THAT CAN BE USED AGAINST BEET INSECTS. 



It will be quickly seen by any one who has taken the pains to go 

 over the foregoing list, that in nearly every case, at least so far as men- 

 tioned here, the insect enemies of the beet are identical with those that 

 work upon our common garden weeds, or else they are such as are very 

 general feeders. It will also be observed that most of them are 

 leaf- feeders ; i. e., they nearly all attack that portion of the plant 

 above ground. These being the facts in the case, the remedies that at 

 once suggest themselves are simple. A spray of some kind scattered 

 over the plants will be effectual as well as economical. The beet tops 

 are seldom utilized for food, either for man or beast. Hence for pro- 

 tection against insects with gnawing mouth parts that attack them an 

 arsenical spray can be used, whilst for such as receive their nourish- 

 ment by means of a sucking month the kerosene emulsion will answer 

 the purpose. This latter remedy will also be effective against No. 27, 

 as has been demonstrated by actual experiment by at least one of our 

 correspondents, who writes that " The kerosene emulsion which you 

 directed me to try on my beets against the flea-beetles was a perfect 

 success." 



A direct as well as useful remedy is the careful destruction of all 

 such weeds as furnish food for the same insects that attack the beet. 

 Clean culture in this case becomes doubly necessary. First, to prevent 

 the appropriation by the weeds of nourishment that should be taken by 

 the beets, and secondly, to give less room for the propagation of inju- 

 rious insects.
