Fruit growers are aware o ortance.of adequate weed control for the production of high '. as high quality. Weeds compete with crops for water, nutrients, and light and are often hosts for insects and diseases.
The first line of defense against weeds is the use of good cultural practices. If there is a choice, select fields without serious weed problems for planting perennial fruit crops. If a field infested with perennial weeds must be used, follow a weed- killing program before the crop is planted.
Cultivation is often the most efficient method of removing weeds from between rows of fruit plants, and herbicide applica- tions should be planned to supplement cultivation practices. Much injury can be done to fruit plants or trees by cultivating too deeply and too close to the plants.
Several generalizations can be made about chemical weed control in fruit crops that may help growers decide the value of a herbicide program for a particular weed problem.
Weeds are killed most easily when conditions favor germina- tion and rapid plant growth. Satisfactory results can be expected if herbicides are applied as directed and under normal conditions. Unusual temperatures or rainfall at the time of, or soon after, application of herbicides may cause unsatisfactory results.
Young weeds are more easily killed than well established

1966 Wee. iç ô.tro1 Recommendations for Fruit Crops weeds. Many herbicide programs for fruit crops are effective only in preventing new weeds from starting.
Soil characteristics, such as clay content and organic-matter level, strongly influence the effect of some herbicides. Heavier soils usually require higher rates of application of herbicides to obtain weed control than do lighter, sandy soils.
It is necessary to apply the correct amount of herbicide uniformly over the control area. In order to do this, quantities of chemicals must be measured carefully, application equipment calibrated accurately, and application made carefully.
Fruit growers should learn as much as possible about the herbicides they are using. Information on loss by evaporation, movement with soil moisture, and limitations of certain weed species will aid in making most effective use of the control pro- grams listed in this leaflet.
Remember: All agricultural chemicals are dangerous if not handled properly. Store in locked compartment away from children and destroy empty containers. Follow manufacturer's safety recommendations as listed on the label.
