Seeds of mungbean were treated with carbofuran 40 F, in 40 EC, dimethoate
30 EC, phosphamidon 100 EC and formothion 25 EC at 1, 3, 5% a.i. on 100 g of
seed. The germination percentage was considerably reduced in all treatments of
dimethoate and in 5% a.i. of monocrotophos. The rest of the treatment were at
par with the control. The radicle length was reduced in all concentrations of
insecticides tested except carbofuran 1% and in 5%. None of the insecticides
tested accelerated the plumular growth. [THH]

control practices for rainfed rice, corn, and grain legumes in three Philippine

Small farmers employ a wide array of traditional and modern insect,
disease, and vertebrate pest control practices. Traditional methods include
religious and magical practices, and the use of plant parts as repellants or
attractants. Hand removal of insects from crops and alarm mechanisms to repel
vertebrate pests are the common mechanical/physical control practices. Farmer
awareness of cultural control practices such as planting time, crop rotation,
increased seeding rate, synchronous planting, and intercropping was high.
Farmers are knowledgeable of the concept of plant resistance to pests and
employ resistant varieties when available; however, they are ignorant of the
role of parasites and predators as biological control agents. Most farmers do
not use fungicides because they do not recognize plant diseases as living
organisms. All farmers have access to knapsack sprayers and use insecticides,
although infrequently and often badly timed. Insecticide applications are often
ineffective because farmers under dose by a factor of 3 to 10. Farmers follow
directions as written on container labels in terms of tablespoons per sprayer
load. However recommended dosages are based on spray volumes of 1,000 L/ha,
whereas farmers average 135 L/ha. [AS]

Several insecticides were screened for the control insect pest of mungbean
on a farmer's field in the Philippines. Monocrotophos, triazophos, phosalone,
deltamethrin, cyanofenphos, fenthion, carbophenothion, and dimethoate performed
well against the beanfly. Although the flea beetle infestation was low, good
control was achieved by all insecticides except tetrachlorvinphos,
phosphamidon, MTMC, fenthion, cartap and bufencarb. All but two insecticides ­
cartap and MTMC - controlled aphids. Highest yields were obtained with
monocrotophos, carbaryl, Metasystox, parathion, deltamethrin, and phosalone
indicating that perhaps other insects were limiting yield. Insignificant yield
responses occurred with malathion, methomyl, ethylan, bufencarb, and EPN.
