Survey on Magnitude of Insecticides Use in Vegetable Crops / Maharjan, R ; S. Aryal ; B. P. Mainali ; Bista, S. ; Manandhar, D.N. ; Giri, Y.P. ; Paneru, R.B.
Title : Survey on Magnitude of Insecticides Use in Vegetable Crops Material Type: printed text Authors: Maharjan, R, Author ; S. Aryal, Author ; B. P. Mainali, Author ; Bista, S., Author ; Manandhar, D.N., Author ; Giri, Y.P., Author ; Paneru, R.B., Author Pagination: 291-298 p. Languages : English (eng) Keywords: insect pests, mid-hills, pesticides, tcrai, vegetable crops Abstract: A survey was carried out in vegetable pocket areas of Dhankuta, Baglung, Dhading (midhills)
and Bara (tercti) Districts with an objective to fitul out the magnitude of pesticide use in
different vegetable crops. A total of 25-35 vegetable farmers were interrogated from each
district using semi-structured questionnaires. Effons were made to gather information on
types of vegetable grown, prevalence of insect pests and diseases, extent of damage caused
by pests and commonly used pest management methods and materials, and pesticide
application frequencies. Data showed that the cabbage, cauliflower, rayo, pea, radish.
carrot, eggplants. onion, different kinds of gourds, cucumber etc are the major vegetable
crops grown in all surveyed districts. Insect pests were identified as the major cause for
quantitative and qualitative loss in vegetable crops in all the districts. Most damaging insects
in the mid-hills in different seasons were aphid, white grub, diamond back moth, cabbage
buttetfly, red ant, cutworms, flea beetles, fntit fly, whereas eggplant shoot and fruit borer,
red pumpkin beetle, fmit fly, cab~age butteifly were found responsible for major damages in
terai plains. All the interrogated farmers applied chemical pesticides for the management of
these pests. The major chemical pesticides that were used for the management of pests like
aphids, diamond back moth and cabbage buttetf/y were metacid, anumite, cypermethrin etc.
and pesticides often used to manage soil insects (red ant, cut worm, white grub) were
clzloropyriphO.\', phorate and malathion dusts. The pesticide frequency of pesticide
application wa~ higher in summer vegetable crops i.e. 10-22 times in a crop season as
compared to wiflter vegetable crops (2-16 times/crop season) in all the four districts.Link for e-copy: http://elibrary.narc.gov.np/?r=517 Survey on Magnitude of Insecticides Use in Vegetable Crops [printed text] / Maharjan, R, Author ; S.

Title : Use of Insecticides on Vegetable Crops in Dhading District Material Type: printed text Authors: Giri, Y.P., Author ; B. P. Mainali, Author ; S.

Languages : English (eng) Keywords: insect pests,, mid-hills, pesticides, vegetable farming, survey Abstract: Vegetable farming has become a profitable business along the roadside of mid-hills of Nepal.
Dhusatar VDC of Dhadhing is one of the vegetable farming pockets located in mid-hill just
82 km away from the capital (Kathmandu). A study was carried out in Dhusatar pocket
during 1999 through focus group discussion and household survey methods in order to
collect the information related with status of pesticide use for the insect pest managemeflt
over existing vegetable growing practices and land use pattern. Majority of cultivated land
was occupied by vegetable fam1ing, especially eggplant and cabbage during summer and
winter season respectively. These vegetables were grown in all types of land (Khet, Bari and
Pakho). Eggplant-cabbage cropping pattern was dominant one. The insect pests such as,
eggplant shoot and fruit borer (Leucinodes orbonalis Guenee), fruit fly (Dacus cucurbitae)
and hoppers (Homopteran) were major problems to crops causing about I 1 to 50% losses in
crop yield through combining pest complex illteraction. Similarly, cabbage butteifly (Pieris
brassicae Doubleday), tobacco caterpillar {Spodoptera litura Fab.), aphids {Aphis sp.),
diamond back moth (Plutella xylostella L). cut worms (Agrotis sp.) and tomato fruit borer
(Helicoverpa armigera Hubner) were major problems in winter season inflicting up to 30%
losses. The use .of chemical insecticides· was oi1ly the means adopted by farmers for· insect
pest management. The chemical pesticide belonging to Syllthetic pyrethroid and
Organophosphate groups were commonly used by the farmers with an increased dose and
frequency over the years. Moreover, the recommended dose, application method and safety
measures for the application of pesticides were also not properly followed by the famlers.
The survey has clearly indicated that majority of famlers were not acquainted with
Integrated Pest Managemeflt approaches and they were willing to adopt methods other thar~
the use of chemical pesticides, if such altemative methods are provided by the line agencies
