The Plant Protection measures help in increasing the per hectare yield by protecting crops from damages of insects, diseases and weeds, because, without effective protection against the attack of pests and diseases, the beneficial outcome of other inputs may not be realized either. In this connection, the Department of Plant Protection provides facilities, such as, locust survey and control; pest control by air on field crops, quarantine of agricultural commodities, and monitoring of pesticides imports, manufacture, formulation, repacking, advertisement, sale, use and quality.
The Pakistan Plant Quarantine Act 1976 and Rules 1967 tare enforced through which the country is protected from the entry and spread of exotic insect pests and disease and trade of plants and plant products is facilitated.
The department maintains 20 aircrafts for locust & crop-pests spray. However, most of these aircraft require repair and replacement. The large scale aerial spraying has been discontinued after transfer of pesticides trade in 1980 to the private sector. At present the Department is conducting free of cost aerial spraying on orchard in Balochistan.
