The Bordeaux mixture described above proved very 

 effective as a repellant during the past year at the Estación 

 Agronómica. The beds treated with it were almost free from 

 insect injuries. 



Where Bordeaux is applied tothe seedbeds, this, together 

 with the use of poison baits, may prove entirely sufficient- 

 Where Bordeaux is not applied or is not effeetive, it may be 

 dcsira ble to use lead arsenate or París greem as indicated 

 later. 



Poison bait.— Cut-worms (cachazudos and mantequillas) 

 are so universally present in Cuban lands in the summer and 

 autumn that we advise the use of poison bait on andaround 

 the seedbeds at the time of planting and oecasionally while 

 the plants are developing. Mr. Houser of this department 

 proved last year in a cooperative experiment with Sr. Anto- 

 nio Suarez at Puerta de Golpe that the cachazudo will eat 

 poison bait scattered among growing tobáceo.

 may be used with equal chances of success sofar as weknow.
