Leersia japonica (Makino) Honda is a perennial weed and currently identified as a new dominant weed species in rice fields in many countries, including China. Here, we studied the biological characteristics combined with nonchemical management of L. japonica to develop a proper control strategy of this weed.

Many studies have demonstrated that tephritid fruit fly larvae are highly susceptible to entomopathogenic nematodes (EPNs) and may become infected as they enter the soil to pupate. However, the susceptibility of adult tephritids and their suitability as EPN targets have been less studied. We performed laboratory assays with 12 Australian EPN strains of Heterorhabditis bacteriophora, Heterorhabditis indica and Heterorhabditis zealandica in adults of the Queensland fruit fly, Bactrocera tryoni. Infective juveniles were delivered in a yeast hydrolysate solution that is attractive to flies. We also measured the flight ability of adults up to 3 days after treatment.

Cnaphalocrocis medinalis is one of the major rice insect pests in Asia. Chlorantraniliprole is one of the most important insecticides for the control of C. medinalis. In this study, a field-resistant population and a susceptible strain of C. medinalis were used to evaluate the inheritance of chlorantraniliprole resistance and fitness costs in the field.

Sparse leaf patch (SLP) is one of the most significant diseases affecting seashore paspalum (Paspalum vaginatum Sw.), caused by Microdochium paspali. Fast and accurate detection of this pathogen is crucial for effective disease management. However, conventional culture-based methods are time-consuming and often compromised by the presence of other saprophytic or endophytic fungi.

Vegetative insecticidal proteins (Vip3) from Bacillus thuringiensis (Bt) have been utilized for control of lepidopteran insect pests. The majority of known Vip3 proteins possess exceptional high toxicity against Noctuid insects such as the fall armyworm (FAW, Spodoptera frugiperda), beet armyworm (BAW, Spodoptera exigua) and cotton bollworm (CBW, Helicoverpa armigera), but generally have relatively low or even no activity against some very important pest insects, such as Asian corn borer (ACB, Ostrinia furnacalis), European corn borer (ECB, Ostrinia nubilalis), rice stem borer (RSB, Chilo suppressalis) and oriental armyworm (OAW, Mythimna separata).

Without controlling weeds, it is estimated that about one third of global crop yields would be lost. Herbicides remain the most effective solution for weed control, but they face multiple challenges, such as the emergence and growth of resistant weed populations. Consequently, there is an urgent need for either herbicides with new modes of action or at least novel chemistries within established modes of action, with outstanding efficacy but without showing cross-resistance to the herbicides present in the prospective markets.

Local vegetable production is susceptible to various fungal pathogens, the most common and lethal of which are Fusarium commune and Rhizoctonia solani. Early detection of these pathogens is challenging, and by the time visual symptoms appear, the pathogens may have already spread extensively, causing massive damage to the production. In this study, we explored the use of hyperspectral data for early detection of diseases caused by F. commune or R. solani in bok choy Brassica rapa subsp. chinensis by collecting hyperspectral data from healthy plants and plants inoculated with either fungal pathogen in a controlled experimental set-up.

As unmanned aerial spraying systems (UASS) usage grows rapidly worldwide, a critical research study was conducted to optimize the simulation of UASS applications, aiming to enhance pesticide delivery efficiency and reduce environmental impact. The study examined several key aspects for accurate simulation of UASS application with lattice Boltzmann method (LBM). Based on these discussions, the most suitable grid size and simulation parameters were selected to create a robust model for optimizing UASS performance in various pest management scenarios, potentially leading to more targeted and sustainable pest control practices.
