“…Results of this study can be important for increasing the sustainability of agricultural systems in Iran and other regions with similar characteristics. Empirical evidence on the role of IPM in reducing pesticide use while sustaining yields and consequently scaling up the sustainability of agricultural systems has been reported for pistachio farmers in Iran and other developing countries (Heidari, 2003;Huan et al, 1999). In addition, the reduction of pesticide use has been one of the main goals among agricultural practitioners in Iran (Rezaei-Moghaddam et al, 2005).…”

Few integrated pest management programs pay specific attention to the decision-making process of farmers in choosing and applying pest management interventions. Thus, practical recommendations provided through extension services frequently fail to be adopted by farmers. A survey of farmers was conducted in the rural area of Arsanjan County in Fars province of southern Iran to explore farmers' perceptions of pesticide efficacy and to evaluate whether these perceptions are reflected in attitudes towards the importance of pest management practices adoption. The study revealed two distinct groups of farmers: group A with farmers who clearly had a positive opinion about the efficacy of the current pesticide products (i.e., they felt that current pesticides are generally effective), and group B with farmers who had a rather negative opinion about the efficacy of the current pesticide products (i.e., they felt that current pesticides are not so effective). Farmers in group A considered IPM principles to be the most important of three areas of pest management practices, they were aware of the potential health hazards of pesticide use, and they were interested in knowing about other alternatives for pest control besides the use of pesticides. By contrast, farmers in group B rated IPM principles as less important, they felt that pesticide use is the sole method of pest control, and they tended to increase pesticide use every year to control pests. Moreover, farmers in group B were not aware of the potential health hazards of pesticide use. Perceptions of pesticide efficacy were found to play a major role in the behavior of farmers towards the use of pesticides and the adoption of alternative methods of pest control such as IPM. Evidently, farmers' perceptions of pesticide efficacy should receive special attention by extension services as a critical point of intervention for rational pesticide use and adoption of IPM programs.

“…Similarly, farmers might gain knowledge from several places, including public information campaigns, other farmers and other extension interventions. For instance, in Vietnam a 'no early spray' media campaign was run at the same time as an FFS programme, and a study comparing farmers who were exposed to the media campaign with those also attending FFS and a comparison group not exposed to either intervention found that beliefs about insecticide spraying changed in both groups and that the two interventions appeared complementary (Huan et al, 1999). In this case, a simple before versus after (pre-test post-test) comparison would have underestimated the impact of the FFS programme.…”

“…Carbamate and organophosphates account for a significant proportion of the total pesticide usage in the delta [2,3], of which the organophosphate diazinon and the carbamate fenobucarb are the most commonly used in rice fields [2,3]. Although they are not persistent in the environment, they are highly toxic to all higher animals because of their specific ability to inhibit acetylcholinesterase (AChE) enzymes, and they can cause malformations of the nervous system [4,5].…”

With the expansion of agricultural areas within the Mekong River Delta in Vietnam, a concurrent, dramatic increase has occurred in agrochemical usage. To date, little consideration has been given to the negative impacts of this agricultural activity on the aquatic resources of the region. Both acute toxicity and subacute effects on brain cholinesterase (ChE) of two of the most commonly used insecticides, diazinon and fenobucarb, on adult native snakehead (Channa striata) were evaluated in a static, nonrenewable system, the environmental parameters of which, such as dissolved oxygen, water temperature, and pH, fluctuated similarly to field conditions. Four levels of insecticides, from 0.008 to 0.52 mg/L (for diazinon) and from 0.11 to 9.35 mg/L (for fenobucarb), were tested to assess the effects on the brain ChE activity of the snakehead up to 30 and 10 d for diazinon and fenobucarb, respectively. Diazinon was highly toxic to this fish species, with a 96-h median lethal concentration (LC50) of only 0.79 mg/L, and it also caused long-term ChE inhibition, with activity still significantly inhibited by 30% after 30 d for the three highest concentrations. Fenobucarb was less toxic to this species, with a 96-h LC50 of 11.4 mg/L. Fenobucarb caused more rapid ChE inhibition but also rapid recovery. The results of the present study indicate an urgent need to regulate the usage of these pesticides in the Mekong River Delta.
