Ferbam Controls Nursery Weeds

Ferbam, a fungicide used on pine nursery seedlings, has given striking pre. emergence weed control in a small test at a south Mississippi forest tree nursery. In this test, Ferbam and allyl alcohol, alone and combined, were applied in water as soil drenches at total rates of 10,890 gallons per acre. Amounts equivalent to 50 gallons of allyl alcohol and 500 pounds of Ferbam per acre were used. Application was in April, 3 days before longleaf pine seed was sown. Sixty-seven days after sowing, the nursery plots were weeded. Green weigh of weeds removed per square foot of nursery bed were: untreated plots 60. 2'_ grams; plots drenched with allyl alcohol, 2.88 grams; plots drenched with Ferbam, 0.25 gram; plots drenched with, both alcohol and Ferbam, 0.12 gram. Neither chemical reduced the density of the seedling stand.
