Insect Management in Peanuts ¹

Richard K. Sprenkel ²

Integrated Pest Management (IPM) programs promote the integration of all applicable control measures to avoid the buildup of damaging populations or to suppress numbers of the pest after it has become established. In general, IPM programs use chemical controls as a last resort and therefore result in reduced pesticide usage, less environmental contamination and delayed development of resistant populations.

Before one of the chemical controls in Table 1 is selected and applied, the kind (species) of insect pest and an estimate of the size of the population must be taken into consideration. This information may be obtained by "scouting" the peanut field. Scouting is a procedure where the crop is sampled in a prescribed manner to determine the presence of damaging population levels.

Sampling Peanuts for Insect Pests

There are several methods that may be used to sample for foliage-feeding pests of peanut. However, the shake-cloth method appears to give the most consistent results for both someone learning to sample peanuts as well as someone who has considerable experience. The shake-cloth or beat-cloth method uses the standard 36" x 36" cloth that is fastened to two dowel rods.

Samples (generally 5-10 random samples covering the field) should be taken weekly during the growing season. Each sample consists of placing the shake-cloth on the ground between the rows of peanuts and vigorously shaking all of the foliage along a 36" section of one row over the cloth. Late in the growing season when foliage from adjoining rows is touching in the middle, it may be necessary to shake the insects from a 36" row onto the ground. If this is done, be sure to look carefully for small larvae which were shaken from the foliage. After the insects shaken from the foliage are identified, counted, and recorded and all samples in the field taken, the numbers need to be summarized to show the average number per foot of row for each pest. To sample for the root-peg-pod feeding pests, select 5 plants in the vicinity of each foliage insect sample. For each plant, use a hand trowel to gently loosen and remove the soil beneath the pegs and pods. Examine the pegs, pods, and roots for evidence of insects and damage that is characteristic of the southern corn rootworm, the wireworm, the burrowing stink bug and the lesser cornstalk borer. Record the number of plants with one or more peg and pod feeding insects present. After all samples in a field have been taken, calculate the percent of plants having lesser cornstalk borers, southern corn rootworm, or wireworm larvae.

Treatment Thresholds

If the average number of foliage feeding pests or the peg-pod-root feeding pests in a field exceeds the thresholds given below, then chemical treatment of the field is usually justified.

Foliage Feeders (Fall armyworms, corn earworms, beet armyworms and loopers)Early Season: 3-4/foot of row (before the plants meet in the middle)

Late Season: 5-6/foot of row (after plants have completely covered the middle)

Peg-Pod Feeders (Lesser cornstalk borer, southern corn rootworm and wireworms)

Before Pegging: 10% of the plants with larvae
After Pegging: 15% of the plants with larvae

Cutworms Treatment is usually justified if cutworm feeding has resulted in 20% or more foliage loss.

Insecticide Usage on Peanuts

Apply insecticides only when needed. Experience has shown that 40-60% of the peanuts will probably not need any insecticide treatments. Over the years there has been a practice of treating for insects and leaf spot at the same time. Current data indicate leaf feeding insects would not require more than two applications during the period of leaf spot treatments. Total defoliation from leaf spot and insects should not exceed 20%. Leaf spot control may be approached on a preventative basis; treat for insect defoliators only as the infestation indicates.

Unnecessary use of insecticides kills beneficial insects and may cause build-up of some pest insects late in the season.

Precautions

Insecticides are poisonous to man and animals and should be handled with care. Read and follow all precautions listed on the pesticide label. Store insecticides in the original labeled containers out of reach of children, pets and livestock and away from food or feed. Dispose of empty containers promptly and safely.
