Chilli (Capsicum annum) is the fourth most important vegetable crop in the world and first in Asia, Anthracnose (fruit rot and die back) caused by Colletotrichum capsici (Syd. Butler and Bisby) is prevalent throughout the chilli growing areas of India. Field experiments were carried out to study the effect of Azoxystrobin 120 + Tebuconazole 240 SC at the rate of 830, 676, and 520ml/ha along with other market fungicides on anthracnose disease of chilli caused by Colletotrichum capsici. Maximum control of C. capsici (15.93, 15.41 and 14.72 after first, second and third spray leaves and fruit respectively) was recorded with 249 g a.i. The fruit yield also has significantly increased recorded the maximum green chilli yield with 9.13 t/ha per cent yield increase over control. No phytotoxic effects such as leaf tip/surface injury, wilting, vein clearing necrosis, epinasty, hyponasty, fruit injury of azoxystrobin 25 SC were observed at the doses of 3320, 1660, and 830 ml/ha. The occurrence of natural enemies spiders, Dragon fly, Damsel fly and wasps population were not affected in the plots treated with Azoxystrobin 120 + Tebuconazole 240 SC @ 830 ml/ha.

Chilli (Capsicum annuum L.) is an important cash crop among the spices. powdery mildew is caused by Leveillula taurica (Lev.) Arn., is a major constraint in chilli production in India, causing heavy yield loss ranging from 14 to 20%. The present study was taken up with an aim to evaluate the Studies of Bioefficacy and phytotoxicity of Azoxystrobin 120 + Tebuconazole 240 SC against Powdery mildew (Leveillula taurica) in Chilli, Experimental findings indicate that efficacy of the fungicidal products of Azoxystrobin 120 + Tebuconazole 240 SC (249 gm/ha, 830ml/ha)to increase crop yield, and disease management of powdery mildew was observed more or less equal to Azoxystrobin 23 % EC, Tebuconazole 25.9 % EC, Myclobutanil 10 % WP and Difenoconazole 25 % EC (Market sample) Among the different doses of Azoxystrobin 120 + Tebuconazole 240 SC plants treated @ 830 ml/ha was recorded highest yield and lowest powdery mildew disease incidence followed by dose 676 ml/ha and 520 ml/ha. When compared to control. The occurrence of natural enemies spiders, Dragon fly, Damsel fly and wasps population were not affected in the plots treated with Azoxystrobin 120 + Tebuconazole 240 SC @ 830 ml/ha Phytotoxicity. The use of Azoxystrobin 120 + Tebuconazole 240 SC fungicide is found to be safe to chilli crop and none of the symptoms like chlorosis, necrosis, scorching, epinasty and hyponasty symptoms were recorded even at the highest dosage of treatment viz., 3320 ml/ha and up to 10 days of after I, II and III spraying.

The present investigation on the effect of integrated nutrient management on growth parameters of chrysanthemum cv. MDU-1 was carried out at the Floriculture complex, Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar. The experiment was laid out in Randomized Block Design (RBD) with 11 treatments with different combinations of inorganic fertilizers (75% RDF, 100% RDF), soil applied organic manures (FYM @ 25 t ha-1 and Vermicompost @ 5 t ha-1) and organic foliar sprays (Panchakavya @ 3%, humic acid @ 0.2% and EM 1:1000 dilutions). Among all the treatments, application of 75% RDF + Vermicompost @ 5t ha-1 along with foliar spray of 0.2% humic acid (T9) recorded maximum values for plant height (20.44 cm, 42.26 cm, 62.56 cm, 72.95 cm at 40, 80,120 and 160DAP respectively), Number of leaves plant-1 (46.31, 82.67, 120.94 and 132.73 at 40, 80, 120 and 160 DAP respectively), leaf area (988.25 cm2 at peak flowering period) and number of branches plant-1 (26.83 at final harvest). The minimum values for the traits were noticed with control T1 - 100% RDF (125:120:20 kg NPK ha-1). [ABSTRACT FROM AUTHOR]

Nerium, botanically called as Nerium odorum L. has been referred as the glory of the garden, belonging to the family Apocynaceae and native of the Mediterranean region extending to subtropical Asia, but are now well distributed in all the tropical and subtropical countries. It is much valued for its exquisitely fragrant flowers which are widely used in making garland, religious offerings and extraction of perfume. Nerium has earned tremendous popularity due to its year round flowering, wide range of shades, varied sizes of flowers with long lasting flower life and dwarf to tall growth habit. It is also used for some medical purposes. In horticulture, auxins, especially IAA, IBA and NAA are commonly applied to stimulate root initiation when rooting cuttings of plants. However, high concentrations of auxin inhibit root elongation and instead enhance adventitious root formation. An experiment was conducted to find out the effect of rooting hormone on root formation of Nerium Var. Pink single at Floriculture research complex in the Department of Horticulture, Faculty of Agriculture, Annamalai University during the year 2017-2018. The semi-hard wood cuttings with 4-5 nodes were treated with different concentration of auxins by quick dip method using IAA, IBA and NAA (1000, 2000, 3000, 4000 and 5000 ppm) along with untreated control and planted during 1st week of November 2017. The results have clearly indicated that 4000 ppm of IBA has given highest percentage of rooted cuttings, no of roots per cuttings, length of longest root, length of basal portion of cuttings showing root, and fresh weight of roots per cuttings. Survival of rooted cuttings was cent percent in all the concentration of IBA. [ABSTRACT FROM AUTHOR]
