Use of agro-chemicals in forage crops is restricted due to the fear of direct toxicity to livestock and risk of pesticide residue accumulation in the food chain. Wheat and barley can be used as green fodder and silage, and herbicide residue estimation in green fodder and silage is important for ensuring the safety of dairy cattle. A field experiment was conducted for two years to study pendimethalin residues in the green fodder and silage of wheat and barley. In both cereal crops, pendimethalin (1.125 kg a.i./ha) was applied as pre-emergence along with an unsprayed control. Pendimethalin residues in fodder, silage, and soil were estimated using gas chromatography-tandem mass spectrometry (GC-MS/MS). At harvest, pendimethalin residues in fodder and silage of wheat and barley were below the limit of quantification (<0.01 mg/kg) during both crop seasons. Pendimethalin can be safely used for weed control in winter cereals grown for fodder and silage.

“…Pesticide residues in green fodder are the major source of pesticides in silage. In addition to the great health risk to ruminants and humans, the types and initial concentrations of pesticides affect the fermentation quality of silage (Ge et al, 2021 ). Zhang, Yu, et al ( 2017 ) found that both chlorpyrifos and chlorantraniliprole increased the butyric acid concentration of alfalfa silage when these two pesticides were sprayed on the surface of alfalfa before ensiling.…”

Lactic acid bacteria (LAB) play pivotal roles in the preservation and fermentation of forage crops in spontaneous or inoculated silages. Highlights of silage LAB over the past decades include the discovery of the roles of LAB in silage bacterial communities and metabolism and the exploration of functional properties. The present article reviews published literature on the effects of LAB on the succession, structure, and functions of silage microbial communities involved in fermentation. Furthermore, the utility of functional LAB in silage preparation including feruloyl esterase‐producing LAB, antimicrobial LAB, lactic acid bacteria with high antioxidant potential, pesticide‐degrading LAB, lactic acid bacteria producing 1,2‐propanediol, and low‐temperature‐tolerant LAB have been described. Compared with conventional LAB, functional LAB produce different effects; specifically, they positively affect animal performance, health, and product quality, among others. In addition, the metabolic profiles of ensiled forages show that plentiful probiotic metabolites with but not limited to antimicrobial, antioxidant, aromatic, and anti‐inflammatory properties are observed in silage. Collectively, the current knowledge on the roles of LAB in crop silage indicates there are great opportunities to develop silage not only as a fermented feed but also as a vehicle of delivery of probiotic substances for animal health and welfare in the future.

“…Synthetic nematicides are a practical and considered fast method to control parasitic nematode. In fact, the chemicals not only harm the environment but also might degrade quality of agriculture products [9]. In addition, the use of synthetic nematodes for an extended period of time will lead nematodes to develop resistance.…”

Root knots, caused by Meloidogyne spp. is among the plant pathogens that lead to significant yield loss in patchouli plants. Farmers have used synthetic nematicides to control the pathogen for many years. In fact, the chemicals not only harm the environment but also might degrade quality of agriculture products. Therefore, in this study, we examined several dosages of Bacillus thuringiensis (Bt) to control Meloidogyne spp. on Pogostemon cablin Benth. Three dosages of Bt suspension (30, 40, and 50 ml/plant) were applied to the rhizosphere to observe the incubation period, disease intensity, number of galls, and the population of nematode. The results show that 40 ml/plant of Bt significantly prolongs the incubation time, reduces the disease intensity, and the number of root-knots. None of the dosages tested showed a significant impact on the nematode population. This study showcases the potential of Bt to control Meloidogyne spp. on patchouli plants. More research is required to confirm the efficacy of this approach.
