Improving Pesticide Uptake Modeling into Potatoes: Considering Tuber Growth Dynamics

نویسندگان

چکیده

To explore pesticide uptake from soil into a growing potato, moving-boundary dynamic model is proposed on the basis of radical diffusion process chemical to sphere. This model, which considers logistic growth potato tuber, describes two hypothetical processes within tuber. The was tested in an illustrative case study for application chlorpyrifos. Results indicate that distribution chlorpyrifos concentrations along radius significantly affected by tuber development. In comparison our results classic using fixed boundary, yields quick and big jump both average concentration bioconcentration factor (BCF) as result sigmoid expansion boundary. Overall, predicts BCFs at harvest are higher than those classical model. measured harvest, shows better performance Our provide new perspective potatoes inform human health risk assessment pesticides applied different stages.

Value Determination of Pesticide Residue-Tested Potatoes*

This study analyzed consumer response to potatoes tested for pesticide residues. These potatoes were packed in five pound bags and priced at three different levels in participating supermarkets. Even when sold at identical prices, consumers continued to favor the traditional round white over the residue-tested potatoes. However, sales of residue-tested were equal at all three price levels, indi...

Water-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes

The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...

A Short Non-Saline Sprinkling Increases the Tuber Weights of Saline Sprinkler Irrigated Potatoes

Previous work has shown that a short non-saline sprinkling, following saline sprinkling, increased crop growth. We incorporated this finding into an investigation of two approaches to the conjunctive use of saline and non-saline water sources for sprinkler irrigation of potatoes viz., (i) mixing waters prior to application, and (ii) keeping waters temporally separate, that is commencing each ir...
