Impact of sowing period, crop distance and seed rate on insect pests
 The incidence of insect pests is generally remain higher in the crops sown/planting at narrow.  Narrow planting helps to increase the moisture and insufficient sunlight which provide favourable condition for the development of insect pests.  Keeping narrow distance between two rows while transplanting the paddy, the population of leaf hoppers and leaf folder are generally higher.  The stem borers infestation is much more in sugarcane field sown at narrow distacne between two rows.  Narrow distance between two rows of cotton increases the various types of sucking insect pests.
 Close planting of groundnut reduces the incidence of aphids.  Changing in sowing period also affect on the incidence of various insect pests.  If sowing of mustard done during the first fortnight of October, the infestation of aphids and sawfly is negligible.  The damage caused by shoot fly is very low in sorghum sown little bit early.  Summer pulses such as green gram and black gram sown in second fortnight of February increases the pest infestation.  Cabbage transplanted in December is more likely to be damaged by aphids.  The damage caused by various sucking pests is very less in early (last week of May) sown cotton.  The incidence of stem borer is very less in maize sown duirng the first fortnight of August.  Keeping the seed rate a little higher than recommended can comensate the loss of seedling due to shoot fly.  Thus, follow recommended sowing time, distance between two rows and seed rate given by Agricultural Univeristy and Agriculture Department and protect your crops against various insect pests.
