Annual leguminous crops such as soybeans and green beans respond to light preplant soil and foliar applications of fertilizer. Beans may not respond to additions of nitrogen (N), phosphorus (P) and potassium (K), especially under the right soil conditions. Beans are able to modify their own root environment to maximize nutrient uptake, especially when the soil pH is 6.0-6.5 and microbes are active in the soil. In addition to these facts, legumes respond to low soil N levels by increasing root nodulation. Symbiotic bacteria in the nodules fix N from the atmosphere so increased nodulation supplies the N necessary for plant growth and development. Make sure that the soil has been inoculated with the correct Rhizobium bacteria to maximize nitrogen fixation. Under most soil conditions a pre-plant application of AGGRAND 4-3-3 in combination with one or two foliar applications of either AGGRAND 4-3-3 OR AGGRAND 0-0-8 are an adequate supplement. A banded application of AGGRAND 0-12-0 and/or AGGRAND 4-3-3 maybe beneficial on cold wet soils or soils that are low in N, P, or K.
Mix 1-2 qts of AGGRAND 0-0-8 and 1-2 gals of AGGRAND 0-12-0 with 25-50 gals. of water and apply to one acre once a month.
1. Mix 1-2 gals. of AGGRAND 4-3-3 with 40-80 gals. of water. Apply as a fine mist with enough solution to thoroughly cover leaves (increase spray volume as crop
develops to ensure thorough coverage). If sufficient nitrogen is present (indicated by dark green leaves), then substitute 1-2 qts. of AGGRAND 0-0-8 mixed
with 20-40 gals. of water. Apply first application when plants are 3-5" in height.
2. Repeat application 2 to 3 weeks before first bloom when tiny hairs on the terminal leaves give plants a shiny appearance.
3. On fresh market green beans a third application before the second flush of blooms stimulates the development of pods during late summer and early fall.
Rates vary according to soil fertility and other inputs used.
Higher dilution rates are more effective than lower dilution rates. Two or three
lighter applications may be more effective than one heavy application. If other
constraints only allow one trip over the field, then do not exceed a 3% dilution
rate (3 gals. of AGGRAND to 100 gals. of water). The addition of a biodegradable
surfactant increases uptake by increasing adhesion to the leaf surface. Apply
AGGRAND in early morning or late evening. Do not apply before or after
rainfall or irrigation. On standard field sprayers use turbo flood jet nozzles when applying AGGRAND to reduce clogging.
To reduce susceptibility to attack of insect and disease causing organisms apply 1 qt. of AGGRANDO-0-8/acre when signs of infestation begin to become apparent -. Some growers are finding that AGGRAND applications alone eliminate the need for pesticide applications on certain pests when they are applied at the same times as pesticides. AGGRAND added to the spray tank reduces the pesticide needed to obtain effective control by 1/4 to 1/2.
Mix 2-3 gals. of AGGRAND 4-3-3 in 20-30 gals. of water. Apply
solution to one acre in spring or fall (apply spring and fall if soil is hard
and low in organic matter) otherwise one pre-plant application is sufficient.
Optimize results by adding 2-3 gals. of AGGRAND 0-12-0 and 1-2 qts. of AGGRAND
0-0-8 to the mix.
