WEED CONTROL WITH NATURAL PRODUCTS NICK CHRISTIANS IOWA STATE UNIVERSITY

THE IDEA CAME FROM AN UNRELATED STUDY ON GRASS DISEASES

FIVE CORN COMPONENTS TESTED CORN MEAL INDUSTRIAL CORN STARCH DRIED CORN GERM CORN SEED FIBER CORN GLUTEN MEAL

BYPRODUCT OF WET MILLING 60% PROTEIN BY WEIGHT 10% NITROGEN BY WEIGHT SOLD AS A FEED MATERIAL FOR CATTLE, POULTRY, FISH, AND DOGS

COULD IT BE USED IN TURF AS A NATURAL FERTILIZER AND AS A WEED CONTROL FOR ANNUALS, LIKE CRABGRASS?

FIELD TESTING BEGAN IN LATE 1980’S EXCELLENT FERTILIZER GOOD WEED CONTROL 20 LBS/1000 SQ. FT. STANDARD PROGRAM: 20 LBS IN SPRING AND 20 LBS IN LATE SUMMER TO EARLY FALL

CONTROL OF ANNUALS APPROXIMATELY 60% FIRST YEAR 80% + IN SECOND YEAR 90% + IN THIRD YEAR

HOW ABOUT PERENNIAL BROADLEAVES?

WHY DOES IT WORK?

DIANNA LIU SOLUBLIZE CORN GLUTEN MEAL HPLC SCREENED 53 METHODS CORN GLUTEN HYDROLYSATE

PREEMERGENCE WEED CONTROL USING PLANT GLUTEN HYDROLYSATES US PATENT 5,290,749

DIPEPTIDES Glutaminyl-glutamine (Gln-Gln) Alaninyl- asparagine (Ala-Asn) Alaninyl-glutamine (Ala-Gln) Glycinyl-alanine (Gly-Ala) Alaninyl-alanine (Ala-Ala)

PREEMERGENCE WEED CONTROL USING DIPEPTIDES ISOLATED FROM CORN GLUTEN HYDROLYSATE US PATENT 5,290,757

LIQUID GOLD ENVIRONMENTAL FACTOR ONTARIO, CANADA

HOW DOES IT WORK?

BRYAN UNRUH CELLULAR CHANGES IN PERENNIAL RYEGRASS ROOTS ASSOCIATED WITH THE ROOT INHIBITING COMPOUND ALANINYL- ALANINE

OBJECTIVES TO STUDY MORPHOLOGICAL AND ANATOMICAL CHANGES IN ROOT CELLS OF PERENNIAL RYEGRASS PLANTS TREATED WITH ALANINYL-ALANINE
