- Abstract:
- ... Granule carriers for insect control agents have been used for many years, especially for control of soil-borne pests. Granular baits have not been practical for foliar application because they do not stick well and are susceptible to removal by wind or rain. A simple and economic technique to prepare adherent granules has been developed. The granules are made of starch which, when applied to wet s ...

- Abstract:
- ... Uptake and persistence of aldicarb residues were measured in five sequential plantings of 'Florunner' peanut, after in-furrow application of aldicarb (1.12 kg[AI]/ha). Gas chromatography was used to determine total toxic aldicarb residues (aldicarb + aldicarb sulfoxide + aldicarb sulfone) in terminal leafbuds from plant emergence until 10 wk after emergence. Residue concentrations were extremely h ...

- Abstract:

Algorithms and computer code (Fortran 77) were developed for computing operating characteristic (OC) and average sample number (ASN) functions for sequential classification sampling plans based on presence-absence counts. Two models that relate the proportion of sample units with more than T (tally threshold) organisms (p(T)) to mean density (m) were considered; an empirical model of the form ln(- ...

Emergence of adults from pots of Brachiaria spp. infested with eggs of A. varia ranged from 55 to 83% and 56 to 80% on susceptible B. decumbens Stapf cv. Basilisk and B. dictyoneura (Fig. & De Not.) Stapf cv. Llanero, respectivel ...

Surveys were sent to University of Nebraska-Lincoln agricultural extension agents, agribusiness personnel (including independent crop consultants), and crop producers identified by extension agents as computer users. There were no diff ...

In spring 1987, 215 (65)Zn-labeled adult plum curculios, Conotrachelus nenuphar (Herbst), were released, just after the emerged from overwintering, at a single site located at the southern edge of a woodlot bordering an unsprayed apple orchard in southern Quebec. At petal fall, between the second and third day of release, a border-row spray of insecticide was applied to the two perimeter rows of a ...

Wheat cultivars previously identified as resistant to the Russian wheat aphid, Diuraphis noxia (Mordvilko), in South Africa and in Idaho were evaluated in the greenhouse to determine the categories of resistance in operation. All test entries tested possessed a significant level of tolerance to D. noxia feeding, based on percentage reductions in plant height. Twenty-one days after infestation, D. ...

The synthetic pheromone mixture was applied in 1,050 plastic twist-tie dispensers and at the rate of 100 g codlemone, 50 g dodecanol, and 10 g of tetradecanol per hectare. Female codling moth antennae give ele ...

- Abstract:

Differences between boric acid and polybor toxicities were significant in 10% sucrose, but not in water. However, borates formulated in water had significantly lower LC50s than those formulated in 10% sucrose. Rate of kill for formul ...

- Abstract:

Six field strains of lesser grain borer, Rhyzopertha dominica (F.), with chlorpyrifosmethyl resistance frequencies of 21-100% and a susceptible laboratory strain were confined on the treated wheat at regular intervals during storage. Thr ...

- Abstract:
- ... Permethrin was aerially applied at 78g (AI)/ha in two experiments to control pale western cutworm, Agrotis orthogonia Morrison, in wheat, Triticum aestivum (L.). Despite low wind and favorable thermal lapse conditions during application, residue analyses showed that only 55 and 78% of the permethrin was deposited on the soil. Spray coverage, as indicated by water-sensitive papers placed on stakes ...

Third-, fourth-, and sixth-instar soybean loopers from two susceptible (laboratory) and eight field strains were exposed to permethrin using a glass-vial technique to estimate concentration-mortality lines. Probit analysis of results from each field strain indicated that ...

The effect of high population densities of citrus bud mite, Aceria sheldoni (Ewing), on the quantity and quality of lemon yields was studied for 4 yr in four commercial groves in coastal southern California. There were two treatments in each grove: treated plots where bud mite was suppressed with acaricide treatments whenever infestation levels increased markedly, and untreated plots where bud mit ...

Esterase patterns were separated by polyacrylamide gel electrophoresis into three groups (GI, GII, GIII) based on their relative mobility (R(m)). Each species had characteristic bands for each group.

The effect of early-season cotton, Gossypium hirsutum L., square loss and insect control (primarily thrips, Frankliniella occidentalis (Pergande)), on the ability of cotton plants to replace lost fruit as well as maintain lint quality was examined in several field trials of differing experimental design in Arizona during 1986-1987. All trials indicated some degree of compensation for damage to fru ...
