Anti Hail Nets To Protect Crops From Hail Can Also Reduce Sudden Temperature Changes:

Microclimate Modification and Insect Pest Exclusion Using Agro insect net Improve Pod Yield and Quality of French Bean.

French bean is among the leading export vegetable in Africa, mostly produced by small-scale farmers.

Unfavorable environmental conditions and heavy infestations by insect pests are among the major constraints limiting production of the crop.

Most French bean producers grow their crop in open fields outdoors subject to harsh environmental conditions and repeatedly spray insecticides in a bid to realize high yield.

This has led to rejection of some of the produce at the export market as a result of stringent limits on maximum residue levels.

Two trials were conducted at the Horticulture Research and Teaching Field, Egerton University, Kenya, to evaluate the potential of using agricultural nets (herein referred to as agronets) to improve the microclimate, reduce pest infestation, and increase the yield and quality of French bean.

A randomized complete block design with five replications was used.

French bean seeds were direct-seeded, sprayed with an alpha-cypermethrin-based insecticide (control), covered with a treated agronet (0.9 mm × 0.7 mm average pore size made of 100 denier yarn knitted into a mesh impregnated with alpha-cypermethrin), or covered with an untreated-agronet (0.9 mm × 0.7 mm average pore size made of 100 denier yarn knitted into a mesh not impregnated with insecticide).
