Kinetics of.the reaction of.2-chloro-3,5-dinitrobenzotrif.ouride with aniline were studied in toluene, metha- nol-toluene binary solvents, benzene and chlorof.rm. The reaction in toluene exhibits third-order kinetics consistent with aggregates of.aniline. Thermodynamic parameters AH#, AS# and AG# are calculated and discussed f.r the reaction of.2-chloro-3,5-dinitrobenzotrif.ouride with aniline in methanol-toluene. Molecular complexes between aniline and the substrate are rejected spectrophotometricaly. The mechanism is studied and compared with the reac- tion in presence of.pyridine. It shows an amine dependence and f.rmation of.homo and/or hetero mixed aggregates between aniline and pyridine i.e. dimer mechanism.

A two-year study was carried out in Giza Agricultural Experiments and Research Station, Agricultural Research Center (ARC), Giza, Egypt in the 2020 and 2021 summer seasons to evaluate the relative tolerance of.ten soybean genotypes f.r cotton leaf.orm inf.station under f.eld conditions. Soybean genotypes H11L145, H155, H113, H4L4, H15L17, H129, H30, H19L96, Giza 111, and Crawf.rd were distributed in randomized complete blocks design with three replications. Soybean genotypes dif.ered signif.cantly f.r cotton leaf.orm at the 6th, 7th, and 8th week f.om sowing. Low values of.cotton leaf.orm assemblages were recorded f.r H113, H4L4, H15L17, Giza 111, and H129. Low percentages of.the larval survival number and weight, as well as the number of.the survival of.pupa were recorded by f.eding on leaves of.genotypes H4f.sub>4, H15L17, and Giza 111 under laboratory conditions. There were signif.cant dif.erences among the studied genotypes in most yield attributes in both seasons. Soybean genotypes H15L17, Giza 111, H113, H129, H19L96, and H4L4 gave higher seed yield per ha, meanwhile soybean genotypes H155, H19L96, H30, Giza 111, and H15L17 had higher seed oil content than the other genotypes in both seasons. The number and weight of.larvae surviving, as well as the number of.pupa survival, were negatively correlated with leaf.total phenols and seed oil content. It can be concluded that soybean genotypes H15L17, H4L4, and Giza 111 are promising genotypes with desirable seed oil content f.r tolerating cotton leaf.orm i

Pesticides are substances used to prevent, destroy or mitigate any pest. We have adopted in this paper the Cellular Automata model to study the dispersion of.the aphids in the block of.citric trees using the pesticides (chemical control) and the biological agent (biological control). The main purpose of.this research is the development of.a simple and specif.c methodology to study Citrus Sudden Death (CSD). CSD is a disease that has af.ected sweet orange trees graf.ed on Rangpur lime in the state of.S?o Paulo-Brazil. Some studies suggest that this disease has been caused by a virus and it is transmitted by insects known as aphids (vector). The ladybug was selected among the most known enemies of.aphids in citrus in Brazil. In order to elaborate a predator-prey type of.model to study the interaction between aphids (preys) and ladybugs (predators) in citriculture we have used a f.zzy rule-based system (f.BS). The states of.the variables of.the system (inputs) are the density of.preys and the density of.predators and their variations are the outputs. Theref.re we take into account the ef.ect of.the wind in the space covered by the aphid, since the wind is important f.r the f.ight of.the aphid as described in Peixoto et al. (2008) [1]. Af.er, we used a f.BS to establish the relationship between the quantity of.pesticides and the density of.the preys. The simulations have been perf.rmed and have been compared between blocks with the presence of.both aphids and ladybugs without the use of.pesticides and the presence of.them with the use of.these ones using the Cellular Automata model. Numerical simulations allow us to f.resee the behavior of.the system, hence creating a spectrum of.possibilities and proposing control techniques f.r dif.erent initial scenarios.
