Urea citrate was synthesized using standard procedure, and its effect on the germination, root and shoot growth of wheat and radish as models for mono and dicotyledonous plants were examined under laboratory conditions. It effectively inhibited the growth of radish roots and shoots; its respective EC 50 values for root and shoot growth was 91.4 and 48.5 ppm. It was formulated as 20% soluble concentrate (SL) and tested in accordance with guidelines established by the WHO and FAO for soluble concentrate formulations, it passed all tests successfully. The formulation was then tested on radish under greenhouse conditions using serial concentrations. It demonstrated a very noticeable effect that appeared as yellowing, dryness, and shrinkage with all concentrations related to exposure periods, and all plants died entirely after 96 hours from treatment in comparison to control.

damaging pest of ABSTRACT The cotton leaf worm, Spodoptera littoralis (Boisd.) is a key pest of cotton and a wide range of economically important crops, vegetables, and fruits in Egypt and worldwide. Emamectin benzoate is a broad-spectrum bioinsecticide that has long been used to control lepidopteran pests such as S. littoralis . The toxicity of emamectin benzoate against S. littoralis fourth-instar larvae and its biochemical effects on their acetylcholinesterase (AChE), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were determined. The toxicity of emamectin benzoate against larvae of S. littoralis was increased by the increase of exposure time. The LC 50 values (lethal concentrations causing 50% larval mortality) caused by emamectin benzoate against S. littoralis larvae were 8.8×10 -2 , 1.1×10 2 and 4.8×10 -3 ppm a.i. at 2, 3 and 4 DAT, respectively. Overall, the application of emamectin benzoate on larvae at concentrations of 4.8×10 -4 , 9.6×10 -4 and 2.4×10 -3 ppm a.i. (concentrations equivalent to 10, 20 and 50% of the estimated LC 50 value at 4 DAT, respectively) increased the activity of AChE, AST, ALT of the treated larvae. The increase rate in the activity of those enzymes was dependent on both the concentration and exposure time for emamectin benzoate.

germination. The present study aims to investigate the effects of hydroxyapatite (HA-NPS) and zinc oxide (ZnO-NPs) Nanoparticles on seed germination of four plant species; ( Raphanus sativus ), ( Solanum lycopersicum ), wheat ( Triticum aestivum L . ) and cucumber ( Cucumis sativus L . ). Seeds were treated with DI-water (control) and nanoparticle suspensions (HA-NPS and ZnO-NPs) solutions, at six concentrations of 10, 20, 50, 100, 200 and 500 ppm. The treatment of HA-NPS showed an inhibition effect on all treated seed germination with significant dose dependence. The inhibition effect was related positively to HA-NPS concentration and was significant at the rate of 50 ppm in radishes and tomatoes, and at 100 ppm in cucumber and wheat seeds. In ZnO-NPs treatment, the inhibition effect was related positively to ZnO-NPs concentration and was significantly started from 20 ppm in radish, tomatoes, and cucumber. Meanwhile, wheat seeds weakly responded to ZnO-NPs inhibition showing a significant effect when applied at 200 ppm. The germination index data (combined seed germination and root elongation), indicated that the response of the tested seeds against Hydroxyapatite Nanoparticles was evident at the highest applied rate (500 ppm), and was as follows: recommend the use

The research was done on tar oil's physical characteristics. It showed that soluble concentrate was the best formulation in which it could be prepared. Its formulation as a 95% soluble concentrate followed standard soluble concentrate formulation procedures. The novel formulation was subsequently subjected to testing using solution concentrates test procedures outlined by the WHO, FAO, and CIPAC. It successfully completed all tests specified. In the lab, the cotton leafworm and cutworm were used to test the novel formula biologically. It had a noticeable impact on the first instar larvae of the two pests under research, however, cotton leafworm was more affected than cutworm since its LC50 was lower (0.5446 ppm as opposed to 1.9029 ppm for cutworm). Additionally, the novel formulations' toxicity and latent effect against cotton leafworm first instar larvae increased with higher concentrations tested as well as longer periods of feeding on the treated leaves. Furthermore, its impact on the developmental stages was also examined; results revealed an inverse association between concentration and pupation percentage, and a direct relationship between malformation and death percentage with the concentration used. The cutworm was more responsive to the new formulation than the cotton leafworm, according to the latent effect investigation. After further necessary investigations are finished, the new tar oil 95% soluble concentrate formulation may be employed to control either cutworm, cotton leafworm, or both.
