Conteúdo: | Brazilian soybean entomologists started developing and implementing and Integrated Pest Management Program on soybeans in 1975. After more than 20 years of implementation, the adoption level is estimated be 35% of the soybean area following a peak of ca. 70% in the 1982/83 season, according to historic series recorded by Embrapa Soja. Net economic returns along the period varies from a conservative estimation of USS$600 million to an optimistic of US$4 billions, varying according to the calculating approach used. For comparison purposes, the gross value of harvested brazilian soybeans for the last season reached US$4.3 billion and the accumulated EMBRAPA's budget for the same period ranked bellow US$4 billions. IPM expansion in Brazil and the main practical aspects of its implementation, as well as restrictions to IPM adoption ate shown. During the last 24 years, the number of insecticide sprayings to control soybean pests were reduced from five to less than one a season. A according to a survey, the use of biological control of velvetbean caterpillar is estimated to cover 10% of Parana State soybean, while the use of the mixture of sodium chloride plus insecticide to control soybean stink bugs has reached almost 25% of the soybean area, in the same state. Insecticide use and its mean number of applications for each one of the soybean pests in also presented, based on information given by 100% of the agronomists of official extension service and 78% of ones working for farmer's co-operatives.
