Chemo-Ecological Insights into the Use of the Non-Host Plant Vegetable Black-Jack to Protect Two Susceptible Solanaceous Crops from Root-Knot Nematode Parasitism

Abstract: Plant parasitic nematodes (PPNs) develop through three major stages in their life cycle: hatching, infection, and reproduction. Interruption of any of these stages can affect their growth and survival. We used screenhouse pot experiments, laboratory in vitro hatching and mortality assays, and chemical analysis to test the hypothesis that the non-host Asteraceae plant vegetable black-jack (Bidens pilosa) suppresses infection of the PPN Meloidogyne incognita in two susceptible Solana...

Effects Of Insecticide Treated Nets In The Management Of Tomato Pests And Their Impact On Natural Enemies And Yield In Nairobi And Murang’a Counties

Tomato is a popular vegetable in Kenya and is extensively grown by small-scale farmers. In spite of the economic benefits to the farmers, insect pests remain one of the most significant constraints to tomato production. Current insect pests control measures rely on pesticides despite the known hazards to human health and the environment. Repeated use of pesticides has also led to the development of resistance by pests. Therefore, it is important to evaluate other pest control strategies ...
