ABSTRACT
The studies on varietal susceptibility, effect of date of sowing and evaluation of trap crops as well as botanical insecticides were carried out to develop eco-friendly management strategy for leaf miner, Liriomyza trifolii (B.) in cucumber, Cucumis sativus Linn. during 2002 and 2003 at Anand Agricultural University, Anand. Out of eight genotypes of cucumber [ACUS 2000-3, ACUS 2000-5, ACUS 2000-6, ACUS 2000-7, ACUS 9 (AAU genotypes), ACUS 5/Gujarat cucumber-1 (AAU variety), Pusa Sanyog, Point Settee (IARI), ACUS 5 was found highly resistant against L. trifolii. Out of 4 sowing dates (1st week of May, June, July and August), 1st week of July was found to be the most appropriate time for sowing of cucumber to minimize incidence of L. trifolii during monsoon. For trapping L. trifolii, castor was found significantly superior than marigold. Cucumber crop surrounded by castor plants recorded less infestation of L. trifolii and higher fruit yield as compared to the cucumber crop surrounded by marigold plants.
Among the four botanical formulations [Gronim 1% EC @ 0.05% (Azadiractin @ 0.0005%); Achook 0.15 EC @ 0.4% (Azadiractin @ 0.0006%); aqueous extract of neem (A. indica) seed kernels and leaves of Naffatiya (I. carnea) evaluated for their field bio-efficacy against L. trifolii, Gronim was found the most effective.
An eco-friendly module consisting of non-insecticidal components [use of resistant variety (ACUS-5), sowing the crop in 1st week of July, raising a row of castor plants (as trap crop) around cucumber crop and three spray applications of Gronim 1% EC @ 0.05 % at 15 days interval starting at 4th week after germination] was found most effective for the management of L. trifolii in cucumber crop as compared to insecticides based module [Use of local variety, sowing the crop in 1st week of June, and spray applications of methyl-o-demeton @ 0.025% followed by endosulfan @ 0.035% and methyl-o-demeton @ 0.025% at 15 days interval starting at 4th weeks after germination] and control [local variety sown in 3rd week of June and kept free from insecticides application].
