During the 1970 kharif season, insecticidal trials were carried out for
controlling insect pests of blackgram, i.e., beanfly (Ophiomyia phaseoli).
galerucid beetle (Madurasia obscurella), and whitefly (Bemisia tabaci), and
mungbean yellow mosaic virus. Three systemic insecticides, viz., aldicarb 10% 1
kg a.i./ha, phorate iO% 1 kg a.i./ha, and monocrotophos 5% 0.75 kg a.i./ha,
were applied in soil at the time of sowing. Three insecticides, viz.,
monocrotophos 60%, metasystox 25%, and phosphamidon 100%, were sprayed twice,
first at 300 ml a.i./ha and second at 500 ml a.i./ha, at 30 and 42 days after
sowing. Treatments of aldicarb + metasystox gave the best control of insect
pests and the treatment of monocrotophos + monocrotophos (granules + sprays)
increased the yield. [THH]

Five granular systemic insecticides were tested in the control of pests
affecting mungbean. Phosfolan, disulfoton, mephosfolan, disulfoton (Solvirex)
and phorate at 1.5 kg a.i./ha were effective in preventing pest infestation at
the early stage of growth of the mungbean. The application of the systemic
insecticides in the soil increased the yield of shelled mungbean from 100 to
500 kg based on the computed yield per hectare. [ASJ

Fourteen insecticides were screened for their effectiveness against pest
insects of mungbean and soybean. In the mungbean trial, methomyl was the most
effective against leaf folders and corn borers, followed by dimethoate,
Ambithion and carbaryl. Carbofuran gave the best control of leaf miners and
leaf rollers, followed by aldicarb. Mungbean plants were stunted and dried
prematurely when the plants were treated with leptophos. In the soybean trial,
all insecticides tested gave significant control of leaf folders. Mephosfolan
gave the best control of cutworms and grasshoppers. [THH]

Germination of wheat and mungbean seeds was used for bioassay to
demonstrate the toxic effects of menazon (S­
1 4 ,6-diamino-s-triazin-2-yl)methyl)]O,O-dimethyl phosphorodithioate),
disulfoton [0,0-diethyl S- [2-(ethylthio)ethyl] phosphorodithioate]), and
GS-14254 (2-methoxy-4-isopropylamino-6-butylamino-s-triazine). At certain
concentrations these pesticides suppressed germination and seedling growth of
these species as a result of impaired respiration, starch, and protein
degradation. Further studies revealed that the pesticides inhibited development
