Tetranychus urticae is the main pest rapidly developing resistance to chemical acaricides used to treat tomato (Lycopersicon esculentum) in the Far North Region of Cameroon. In an effort to develop an alternative tomato production strategy, a survey was undertaken on 100 producers to collect information on this crop and field experimentation to determine the effectiveness of the powder of neem seeds was performed. tomato,The results show that 63.2% of producers recognize tomato pests. Mites are the most important followed by whiteflies. Producers protect their culture with chemical pesticides (70%) or with available products: soap (26%); cow urine (30%). 82% use the neem seed to treat tomato crops. Treatment with neem seed powder shows that it improves the development of tomato (P > 0.05) and fruit yield (977 fruit) compared to the control (514 fruit), although it remains below the treatment with chemical acaricide Acarius (1464 fruits). Neem seed powder effectively protects tomato against T. urticae.
