Spray Applications

Spray applications enable a uniform distribution of substances on surfaces in a highly efficient manner, and thus can be found at workplaces as well as in consumer environments. A systematic literature review on modelling exposure by spraying activities has been conducted and status and further needs have been discussed with experts at a symposium. This review summarizes the current knowledge about models and their level of conservatism and accuracy. We found that extraction of relevant information on model performance for spraying from published studies and interpretation of model accuracy proved to be challenging, as the studies often accounted for only a small part of potential spray applications. To achieve a better quality of exposure estimates in the future, more systematic evaluation of models is beneficial, taking into account a representative variety of spray equipment and application patterns. Model predictions could be improved by more accurate consideration of variation in spray equipment. Inter-model harmonization with regard to spray input parameters and appropriate grouping of spray exposure situations is recommended. From a user perspective, a platform or database with information on different spraying equipment and techniques and agreed standard parameters for specific spraying scenarios from different regulations may be useful.

Spray Applications

The efficacy of sulfonylurea herbicides impregnated on granular fertilizers applied PPI or POST was compared to broadcast spray applications for annual broadleaf weed control in winter wheat. Henbit and bushy wallflower were controlled by chlorsulfuron or triasulfuron impregnated onto diammonium phosphate granular fertilizer applied PPI. Efficacy of these herbicides for annual broadleaf weed control was reduced by applying them POST with granular urea fertilizer carrier instead of with water carrier.

Spray Applications

Spray applications of 4.2% Off-Shoot-0 (a mixture of methyl ester of fatty acids C6, C8, C10, and C12) effectively destroyed flower bud scales and flower parts on the azalea (Rhododendron simsii Plachon.) cultivars ‘Prize’ and ‘Kingfisher’. The addition of ethephon to Off-Shoot-0 did not increase the destruction of bud scales and flower parts. Dikegulac-sodium and oxathiin alone or in combination with ethephon did not significantly destroy scales or flower parts. Destructive chemical pinching agents such as dimethyl dodecylamine and n-undecanol usually were as effective as Off-Shoot-0 in killing bud scales but not flower parts. Cultivars differed slightly in their response to chemicals designed to destroy unwanted flower buds.

Spray Applications

Spirotetramat (Movento) is a systemic insecticide that is used to control scale insects on kiwifruit The use of protectant copper sprays on kiwifruit has become increasingly common due to the bacterial disease Pseudomonas syringae pv actinidiae This study investigated the interaction of copper with spirotetramat and how it influenced the uptake and translocation of spirotetramat within the plant Movento 100SC sprays should not be tank with copper sprays because the uptake and translocation of spirotetramat is likely to be compromised These negative effects were minimised when an organosilicone/organic fluid blend adjuvant (DuWett) was included in the tank mix Preand post spray applications of copper at least 1 week either side of spirotetramat applications are unlikely to significantly affect the uptake and translocation of spirotetramat and thus have any effect on its activity There were no marked differences between two commercial copper formulations in their effects on spirotetramat uptake but minor differences in translocation were observed

As determined by the length for which roots were killed, there was no diurnal variation in the effectiveness on skeleton weed (Chondrilla juncea L.) of spray applications of 'Methoxone' at two-hourly intervals over a period of 24 hours. As determined by reduction in growth above the primary leaves, there was a well-marked diurnal variation in the effectiveness on bean plants (Phaseolus vulgaris L.) of drop applications of 'Methoxone.'
