Alfalfa in the second cutting had better growth compared to the first cutting, so that the plant produced the highest fresh and dry yield in the second cutting. However, weed non-interference increased the levels of superior morphological traits of alfalfa, such as fresh and dry yield, plant height, and number of leaves per plant, number of main-stem nodes, leaf area and p...

Control strategies of papaya mealybug, Paracoccus marginatus Williams & Willink infesting vegetable crops in Bangladesh
...s, ornamental plants and weeds of economic value. The papaya mealybug feeds on the sap of the plants by inserting its stylets into the epidermis of the leaf as well as into the fruit and stem. In doing so, it injects a toxic substance into the leaves. The result is chlorosis, plant stunting, leaf deformation, early dropping of the leaves and fruits, a heavy accumulation of honeydew and death of the host plants. Heavy infestation is capable of making fruits ine...

Among them 25 species of insects, 4 species of mites and 10 species of nematodes are recorded from Bangladesh. Enormous crop loss was incurred due to the attack of these pests and largely responsible for the declining productivity of tea. Extensive use of chemical pesticides began only a few decades ago with tremendous immediate econo...

The residual/carryover herbicides may influence sowing decisions for the next crop due to reduced herbicide breakdown. The present study aimed at exploring the contribution of bio-fertilizer microbes (Azospirillum) to mitigate the inhibitory effect of herbicide residue in soil, and their inhibitory effect on weed seeds.

In conservation tillage systems, the interaction between fertilizers and weeds is very complex, and there are reports of positive as well as negative correlations with weed establishment. Altered physical and chemical properties of reduced-tillage soils result in different weed growth and weed-crop competition periods and thus have indirect impacts on weed control strategies and management opt...
