Whitegrub: Holotrichia consanguinea (Melolonthidae: Coleoptera)
 

Distribution and status: Throughout India
Host range: Maize, sorghum, pearl millet, peppers, bhendi, and brinjal

Crown drying, followed by leaf yellowing and wilting. When pulled, affected canes easily come off. cause significant root damage. 'C'-shaped grubs with a whitish yellow colour that are near to the base of the clump. In the monsoon season, adults are dark brown and drawn to neem trees.


 

Management

·        cultivate hardy plants like Co 6304, Co 1158, and Co 5510

·        Set up a light trap to draw adults in and kill them.

·        Don't forget to irrigate

·        Rotation of crops in endemic regions

·        Neem, Ailanthus, and Acacia adult beetles should be gathered and destroyed.

  Red cotton bug:  Dysdercus cingulatus  (Pyrrhocoridae: Hemiptera)   Distribution and status:  Tropical Africa, Tropical Asia, Australia, the United States, Central and South America, India, and Uttar Pradesh, Bihar, Bombay, and Andhra Pradesh. At crop maturity, a common pest. Host Plants:  Silk cotton, maize, hollyhocks, pearl millet, bhendi, clover, and sorghum.  Damage symptoms:  Both nymphs and adults are responsible for the damage since they discolour the lint and suck up plant and boll sap. As a result, they are also known as cotton boll stains. The bugs tend to gather in large groups. Attacked seeds become less viable. Nematospora gossypii enters the wound site and discolours the fibre. Bionomics:  The adult is an insect with ventral white stripes on its abdomen that is red and black. In the earth, the eggs are placed in irregular heaps. The bug has a fecundity between 100 and 130. 4- to 7-day egg period. Six instars are req...

PLANT GROWTH REGULATORS (PGRS)

-
  PLANT GROWTH REGULATORS (PGRS) Plant growth regulators (PGRs) are naturally occurring chemicals that govern several aspects of plant growth and development. They are sometimes referred to as phytohormones or plant hormones. They are essential to several activities, including the germination of seeds, the development of roots, blooming, ripening of fruit, and reactions to external stimuli. The following describes several important regulators of plant growth: 1. Auxins: Ø Function: Promote fruit growth, apical dominance, root initiation, and cell elongation. Ø Natural Sources: The main natural auxin is indole-3-acetic acid (IAA). Ø Auxins from synthetic sources, such as naphthalene acetic acid (NAA) and indole-3-butyric acid (IBA), are extensively utilized in agriculture. 2. Gibberellins (GAs): Ø Encourage blooming, seed germination, and stem elongation as its functions. Ø Natural Sources: One frequent naturally occurring gibberellin is gibberellic acid (GA3). ...
