Seed coating is a method of encasing seeds in adhesive materials to improve germination and performance while lowering cost. Seed coating has been widely used in agriculture as an efficient way to reduce biotic and abiotic stressors, hence boosting crop growth, productivity, and health, in order to satisfy the demands of the development of precision agriculture. Plant-beneficial microorganisms include Trichoderma, rhizobium, arbuscular mycorrhizal fungusfungi and plant growth-promoting bacteria. Fungicide seed treatment is easy, affordable, and efficient. Additionally, it is well known that the selection of chemicals for seed treatment also has a favourable impact on seed viability and vigour during germination storage. Seed coating polymers are utilised in conjunction with active components like fungicides and insecticides. A new era of biocontrol techniques has recently begun. By utilising hostile microbes to fight seed-borne illnesses, new technology is being developed. Beneficial fungus like Trichoderma harzianum and Trichoderma viride are among the bioagents most powerful and efficient fungus- and soil-borne pathogen suppressants such as seedling blight, collar rot, stem rot, root rot, dry root rot, and their use may can effectively manage each of these illnesses, and thus encourage crop growth and yield.
RÉSUMÉ
Lead and cadmium accumulation examined in shoot and leaf tissues of seedlings of mustard (Brassica juncea cv RH-30), at 7th day, treated with either putrescine (1 mM), or ammonium nitrate (10 mM) or IAA (10 microM). These were included in the nutrient medium, containing Pb or Cd (0.1 mM and 2 mM). Metal accumulation was more in shoot than in leaf tissues, which was increased manifold under saline conditions. However, Cd accumulation in tissues was higher than Pb. Chemical (putrescine, ammonium nitrate or IAA) treatment of the seedlings, decreased metal accumulation in leaf (10-20%) and in shoot (40 to 60%) tissues, depending upon external metal levels. Putrescine significantly decreased the metal accumulation and translocation under saline conditions.

The present study was conducted in 30 cases of snake bite to understand fully the intricacies of the cardiac profile and to render help in the management of the problem arising out of them. All were subjected to routine and specific investigations (ECG, X-ray Chest, SGOT). The present study concluded that 57 per cent of patients of snake bite were in 2nd and 3rd decades of life. Viperine snake bite occurred in 93 per cent and elapide snake bite in 7 per cent of cases. Cardiotoxicity was seen in only 25 per cent patients with viperine bite. Seventy-six per cent of the patients presented within 24 hours of the bite. Seventy per cent of patients had haemorrhagic manifestations and 30 per cent had cardiotoxicity. The disturbance in heart rate was seen in 47 per cent, rhythm disturbance in 6.7 per cent, tachycardia in 36.7 per cent and bradycardia in 10 per cent cases. Hypertension was found in 6.7 per cent, hypotension in 16.7 per cent. Thirty per cent of patients had gallop rhythm and it persisted in 16.6 per cent patients till discharge. One patient had evidence of pulmonary edema and one had basal congestion. Cardiomegaly on chest X-ray was found in one patient and elevated SGOT titres were found in ten per cent. Common electrocardiographic changes were sinus tachycardia, sinus arrhythmia (6.6%), sinus bradycardia (10%), tall T-wave in V2 (3.3%), pattern suggestive of acute anterior wall infarction with reciprocal changes (3.3%), myocardial ischemia (10%), non-specific ST-T changes (16.7%) and atrioventricular block (3.3%). The mortality rate was 10 per cent and all these patients had bleeding manifestations and abnormal electrocardiograms.
