In agricultural production, carbendazim and other pesticides are used to prevent soybean root rot. However, degrades slowly affects a series of biochemical processes such as soil biological nitrogen fixation nutrient activation in the natural environment. This study mainly investigated effects Rhizophagus intraradices, Acinetobacter calcoaceticus, on biomass, incidence rot, total number bacteri...

Pesticide exposure is one of the most important occupational risks in Thailand. A specific community based participatory model to reduce pesticide risk behaviors among rubber farmers in the Southern of Thailand remains limited. The study objectives were: (1) to develop community based participatory model to reduce pesticide risk behaviors among rubber farmers; and (2) to evaluate their knowledg...

AIM This study assesses the association between pesticide exposure in pregnancy, preterm birth (PTB) and shortened gestation. METHODS Pregnancy information was abstracted from the Centers for Disease Control (CDC) Non-Public Use Natality Datasets 1990-2005. Pesticide use in maternal county of residence was calculated using California Pesticide Use Reporting (PUR) data 1990-2005. Counties were...

Agricultural pesticide use in Viet Nam has more than tripled since 1990. However, pesticide legislation and regulations have not been developed in response to this large increase in usage, as a result of which pesticides pose a serious threat to human health and the environment. This paper identifies the need to improve pesticide regulations in Viet Nam through a comparative analysis of pestici...

Pesticide runoff from impervious surfaces is a significant cause of aquatic contamination and ecologic toxicity in urban waterways. Effective mitigation requires better understanding and prediction of off-site transport processes. Presented here is a comprehensive study on pesticide washoff from concrete surfaces, including washoff tests, experimental data analysis, model development, and appli...

After a pest develops resistance to a pesticide, switching between different unrelated pesticides is a common management option, but this raises the following questions: (1) What is the optimal frequency of pesticide use? (2) How do the frequencies of pesticide applications affect the evolution of pesticide resistance? (3) How can the time when the pest population reaches the economic injury le...

Background Pesticide self-poisoning is a major problem in Bangladesh. Over the past 20-years, the Bangladesh government has introduced pesticide legislation and banned highly hazardous pesticides (HHPs) from agricultural use. We aimed to assess the impacts of pesticide bans on suicide and on agricultural production. Methods We obtained data on unnatural deaths from the Statistics Division of ...

Recent studies by agriculture researchers in Pakistan have shown that attempts of crop yield maximization through pro-pesticide state policies have led to a dangerously high pesticide usage. These studies have reported a negative correlation between pesticide usage and crop yield in Pakistan. Hence excessive use (or abuse) of pesticides is harming the farmers with adverse financial, environment...
