Effectiveness of a plant-shake method of sampling soybean Lepidoptera was evaluated. Laboratory-reared larvae were hand-infested and allowed to feed on the plants for 15 min or 24 h, depending upon the test. About 50% of introduced small larvae would be recovered on the dropcloth from pod-set to pod-fill and a ca. 60% at the green bean stage; ca. 66% of medium and large larvae would be recovered from pod-set to pod-fill and ca. 75% at the green bean stage. About 4-5% more Anticarsia gemmatalis Hubner of Heliothis zea (Boddie) than Pseudoplusia includens (Walker) were recovered. One sampler recovered ca. 8% more larvae than another. Calibration ratios for the plant-shake method are presented. |

The objective of this work was to evaluate the solubility of the micronutrients copper, nickel, and zinc, chemically extracted from silicate agrominerals, as alternative sources of potassium for lettuce (Lactuca sativa) and rice (Oryza sativa) cultures, as well as their availability to the plants. The micronutrient contents of five agrominerals (alkaline ultramafic, biotite schist, volcanic breccia, phlogopite schist, and mining by-product from Chapada) were evaluated, after being extracted by the citric acid, hydrochloric acid, diethylenetriaminepentaacetic acid, 3051A, neutral ammonium citrate, and Mehlich-3 methods. The agrominerals, at the doses of 0 (control), 200, 400, and 600 kg ha-1 K, were mixed to soil where lettuce and rice were cultivated. The agrominerals presented a low solubility of Ni, Cu, and Zn, with lower contents in lettuce shoots and rice grains than the corresponding soluble standards in sulfate form. The availability of micronutrients to the plants increased with the use of agrominerals, in comparison with the control. Similarities were observed in micronutrient solubility and availability between the different groups of agrominerals. The solubility and availability of Cu, Ni, and Zn depend on the solubility of the minerals that compose the agrominerals. |
