| Abstract: | This study presents
InfoCrop-rice model to simulate damage mechanism of brown planthopper (BPH), Nilaparvata lugens (Stal.) on two rice
cultivars (Pusa Basmati 1 and ADT-38). Simulated yield and TDM losses were
proximal to respective observed losses of yield (R2 = 0.801; RMSE =
18.47%) and TDM (R2 = 0.843; 20. 73%), indicating proper validation
of damage mechanism of BPH. Validated model simulated economic injury levels
(EILs) of BPH at different rice growth stages with two control expenditures,
incurred on two applications with each of monocrotophos 36 WSC @ 500 g a.i./ha
and buprofezin 25 SC @ 100 g a.i./ha and three market prices of Pusa Basmati 1
and ADT-38 apiece. EIL exhibited
a negative relationship with market value of produce but had a positive with
control measure expenditure. |
