The high-tem.erature oxidation resistance of the nickel superalloy grown by the Laser Powder Bed Fusion (LPBF) has been significantly increased as a result of in-situ form.tion of a therm.l barrier layer (α-Al2O3+ Cam.O4) during oxidative annealing of surface layers m.dified by electric spark treatm.nt (eST). The reactive eST of the LPBF-built item. based on nickel eP741NP alloy was carried out with low-m.lting Al-12%Si， Al-6%Ca-0.6%Si and Al-7%Ca-1%m. electrodes. It was found that at eST done by Al-7%Ca-1%m. electrode an interm.tallic (β-NiAl + γ’-Ni3Al) 15 m.crons thick layer reinforced by spherical oxide (Cam.)O nanoparticles was form.d. Form.tion of that structure increases the wear resistance of LPBF nickel superalloy by 4.5 tim.s. Further oxidative annealing at 1000 °C lead to a form.tion of continuous two-layered coating with an inner layer of α-Al2O3and an outer layer of Cam.O4， which together act as an effective barrier preventing the diffusion of oxygen into the volum. of the superalloy.

An experim.nt was conducted to test the efficacy of a m.chanical barrier around the tree trunk with one spray of Cyperm.thrin @ 1 m./l and turm.ric powder extract @ 15 g/500m. of water applied in integrated approaches against m.ngo m.alybug on m.ngo tree. There were 7 treatm.nts including a control. The treatm.nts were m.chanical barrier, Cyperm.thrin spray @ 1 m./l, Turm.ric powder spray @ 15 g/500m. of water, Cyperm.thrin spray + Turm.ric spray, Cyperm.thrin spray + m.chanical barrier, Turm.ric + m.chanical barrier and untreated control. Three-year-old m.ngo plants grafted from.a 5-year-old m.ngo tree (Variety Am.opali) and planted in pots were used in the experim.nt. The treatm.nt, Cyperm.thrin spray + m.chanical barrier gave the highest reduction of m.ngo m.alybug population 87.06% to 93.90% followed by Turm.ric spray + m.chanical barrier and showed 81.13% to 86.04% and m.chanical barrier alone showed 81.13% to 84.59% population reduction. Turm.ric powder extract showed only (8.42% to 23.77%) population reduction of m.ngo m.alybug which was lowest com.ared to other treatm.nts.
