Above all, watch the seeding rate . 



Pay no attention to rumor and do not panic as some have done. This seed treatment 

 is a good practice. As with all new practices, some difficulties will be encountered. 

 It will require that a bit more care be taken when planting. Many farmers who have 

 examined their planter boxes at regular intervals reported to us that they had no 

 problems. Furthermore, many have asked about using diazinon seed treatment and root- 

 worm insecticides. Except for BUXten, aldrin, or heptachlor, the rootworm insecticides 

 should control these beetles. 



Flea beetles are common in early planted sweet corn in the southwestern part of the 

 state. Fields of newly emerging corn should be observed often for these shiny, 

 black, jumping beetles. They strip-out narrow lines on the corn leaves, leaving 

 only white tissue. If damage is occurring and plants are dying, apply either 3/4 

 pound of carbaryl (Sevin)- -preferred on dairy farms --or 1-1/2 pounds of toxaphene 

 per acre as a band over the corn row. Also, treat grassy areas bordering the field, 

 such as fence rows or ditchs, to prevent additional flea beetles from moving into 

 the corn. Do not use carbaryl near beehives or toxaphene near fish-bearing waters. 



HOMEOWNER INSECT PROBLEMS 



Roaches in the home can be controlled with a spray of 0.5-percent diazinon in oil, 

 applied to their runways and hiding places . This material can be purchased in a 

 pressurized spray can. Also, Baygon was recently approved for use in the home and 

 can be purchased in pressurized cans. Brown-banded roaches require a more-thorough 

 treatment than the other, more-common species. 



Oystershell scale eggs have begun to hatch, especially on lilac, and the newly 

 hatched crawlers are moving out on new growth. Thorough spraying with malathion 

 (2 teaspoons of 50- to 57 -percent liquid concentrate per gallon of spray) at this 

 time will provide good control of these crawlers. The old scale coverings will 

 probably remain on the bark for a while, but they will eventually slough-off.

 POSTEMERGENCE CORN TREATMENTS 



Although Ramrod is primarily used as a preemergence material at planting time, 

 Ramrod wettable powder is cleared for early postemergence spray applications for 

 corn until grass weeds reach the two-leaf stage. 



Fairly good results have come in from Agronomy Department trials with this early 

 postemergence treatment. But the sooner application can be made after planting, 

 the better. Corn tolerance has been good for both preemergence and early post- 

 emergence Ramrod applications . 



You don't have to wait until you see the weeds. Ramrod can be applied anytime be- 

 fore the weeds or crop emerge. You can still make an application until the weeds 

 have two leaves. But don't stretch your luck by applying Ramrod to bigger weeds.
