Due to its difficult detection, there is little knowledge about the occurrence and the properties of microscopic leaf wetness. Whitehead K, Karr N, Mitragotri S. Holloway PJ, Rees RT, Stock D. Honey bees serve as an optimal terrestrial bioindicator to determine if 'the formulation and not just the dose makes the poison'.

Measurement of cuticular penetration. However, the track-sprayer results were very different from the field results, with amounts of adaxial and abaxial retention and total deposition much lower. As an adjuvant a weak nonionic penetrant , urea Fischer Chemical, Fair Lawn, NJ was added to Kocide at a concentration of 1. The literature has been reviewed and references are presented to provide an overview of organosilicones as adjuvants for agrochemicals. Observe all label directions and precautions while using these products. Home Products Helena Products Adjuvants Dyne-Amic. The literature reviewed demonstrates the sound science base on which this novel class of organosilicone adjuvant chemistry rests.
Adjuvants Affect Penetration of Copper Through Isolated Cuticles of Citrus Leaves and Fruit
The weight per unit area, an estimate of cuticle thickness, of cuticles isolated from the abaxial side of grapefruit leaves as well as from the equatorial plane of fruit was lower than that of cuticles isolated from adaxial side of leaves Table 1. Copper-based fungicides, used either alone or with spray oil, can successfully control greasy spot, melanose, citrus scab, Alternaria brown spot, and Phytophthora rot and citrus canker Rogers and Timmer, Adjuvants such as sodium carbonate, and especially slaked lime, significantly decreased the damaging effects of Cu Brodrick, , perhaps because both sodium carbonate and slaked lime increased the pH of spray suspensions causing Cu to precipitate from solution Parker, , thereby leaving less Cu in solution available for penetration. Hardwoods have been shown to have a consistent negative growth impact on pines, and uncontrolled hardwoods continue to compete aggressively with pines throughout a rotation, especially when hardwoods remain in the pine canopy. Davis , Michael J.
Description: For each type of cuticle, the batch of data representing penetration of one Cu preparation was compared with penetration data obtained with four other Cu preparations.
