the berries. This is according to an interpretation obtained from Mr. James Toughy 

 of the Federal EPA Insecticide and Rodenticide Branch. There is no tolerance for 

 metaldehyde residues on fruits and vegetables. 



A new slug and snail bait called "Mesurol" has been cleared for use around ornamen- 

 tal plants, flowers, greenhouse plants, and structures. It cannot be used on food 

 crops or directly on plant foliage. First, lightly water the area to be treated. 

 Then, scatter the bait on the soil beneath the plants so that it can hardly be seen. 

 Check the label for use directions. 



Striped cucumber beetles are moving from overwintering sites to newly emerging cu- 

 cumbers , squash, and similar vine crops in home vegetable gardens. Cucumber beetles 

 feed on the new leaves, eating holes in them; but their greatest damage results from 

 the bacterial wilt disease they often transmit to young plants. Infected plants will 

 often wilt and die suddenly, after being fed on by the beetles. Carbaryl (Sevin) ap- 

 plied as a 5-percent dust or a spray using 2 tablespoons of 50-percent wettable powder 

 per gallon of water will control these beetles . 



WEEDS 



CORN WEED CONTROL 



Late Applications of Preemergence Herbicides . In the rushed planting schedule this 

 spring, a considerable amount of corn was planted without a preemergence herbicide. 

 We are now receiving calls about "late applications" of preemergence herbicides. Here 

 are our suggestions: 



Lasso or Ramrod and their combinations with AAtrex (atrazine) can be applied until an- 

 nual grasses have two leaves. The earlier the application, the more effective the 

 treatment. If possible, a timely rotary hoeing will help keep many small weeds under 

 control . 



AAtrex, Bladex or Outfox can be applied until annual grasses are 1-1/2 inches tall. 

 Tli is is usually within two or three weeks of planting. Applying these herbicides to 

 corn that is growing under stress can cause yellowing and stunting. This injury is 

 usually temporary, but occasionally has been serious. 



Do NOT add any wetting agent or oil to Bladex, or serious crop injury may result. Out- 

 fox is already formulated in oil. An emulsifiable oil added to AAtrex will help kill 

 weeds more rapidly. 



Household Detergents as Additives . Every year about this time we receive a lot of 

 questions about using household detergents as additives for postemergence herbicide 

 sprays. These are often claimed to substitute for emulsifiable oils or agricultural 

 surfactants. Studies with various additives indicate that the nonphytotoxic crop oils 

 are more effective for weed control than products originally intended for use as house- 

 hold detergents. 



It is usually advisable- -and often more economical --to use emulsifiable oils or agri- 

 cultural surfactants that are especially formulated for agricultural use. Do not use 

 surfactants, crop oils or other additives with any herbicide unless such a mixture is 

 specified on the herbicide label. An additive that improves weed kill may also in- 

 crease crop injury.
