Coating the wheat seeds with 25 g ginger juice mixed in water per 0.25 ha of land before sowing. Proving successful, he later modified the method. He collected 250-300 ml juice of onion and ginger mixture without water in tin and allowed drops of the juice to fall from a small hole into the irrigation channel.Chimanbhai Ambalal Patel of the same village in Kheda district also followed the method with success.
Crop: wheat, pigeon pea, cotton
Crop Family: Poaceae, Fabaceae, Malvaceae
Crop Scientific Name: (Triticum aestivum), (Cajanus cajan), (Gossypium hirsutum)
Crop Vernacular Name: GHAU, TUVER, KAPAS
Formulation: Expecting that pungent material might be useful in killing the termites, he extracted juice out of onion (Allium cepa) bulbs and ginger (Zingiber officinalis) rhizomes and poured the same on termites due to which the termites were killed.
Ingredients: Juice of Onion (Allium cepa) and Ginger (Zingiber officinalis)
"Despite playing significant role as agricultural pests, termites attracted less attention of researchers in India; on both fronts - traditional and frontier techniques. Present paper is an attempt to collect and compile Indian Indigenous Traditional Knowledge (ITK) from various sources on termite management aspects in light of various key-components (cultural, physical, mechanical, biological, etc.) of Integrated Pest Management (IPM) under the aegis of Integrated Crop Management (ICM). We undertook a comprehensive review of farmers’ ITK across India especially in seventeen states in detail, in an effort to outline the underlying principles for termite management. This review confirmed existence of affluent knowledge of local inhabitants/aborigines on termite and their management. Various ITK in termite control is used across India. Review analysis revealed that in some places of India, termites are being used as indicator of various environmental aspects, viz. anticipated rainfall, soil fertility, etc., soil of termite mounds were reported to be used in low risk farming strategies. Use of locally available plants for termite control was a common practice in Indian subcontinent since ages."

"Study was conducted to evaluate the toxicity and repellency of Zingiber officinale, Allium sativum, Dennettia tripetala and Capsicum annuum applied as individual and mixed extracts against termites (M. bellicocus) under laboratory and field conditions in Abraka. The experiment was replicated trice with 0.21% Diazinon (a synthetic insecticide) and distilled water as a standard check and untreated control respectively. The result revealed that as concentration of all plant extracts increased, mortality was significant (p< 0.05) after 72hours of exposure. The mixture of Z. officinale + A. sativum was most toxic having the least LC50 of 7.41mgL-1, LT50 of 34hrs and a repellency value of 88.89%. Extracts of C. annuum, D. tripitala, A.sativum and their mixtures were very effective against termites after 30 days of post treatment in the field because the termitaria were not rebuilt. However, the efficacy of the extract of Z. officinale applied singly against termites was slightly reduced after 24 days of post application. All plant botanicals maybe used as plant termiticides as they are readily available and cheap to purchase."

"Onion (Allium cepa) and garlic (Allium sativum) as pest controlintercrops in cabbage based intercrop systems in Zimbabwe - Cultural methods can be implemented to reduce the problems that have been caused by indiscriminate use of insecticides. An experiment was carried out in Makonde District, Zimbabwe to determine the ability of onion and garlic to reduce pest problem when intercropped with cabbages. A randomised complete block design was used with five treatments replicated three times. The treatments were (1) cabbage intercropped with garlic within rows, (2) cabbage intercropped with onion within rows (3) Cabbage and onion intercropped within rows (4) Cabbage and garlic intercropped within rows and (5) Sole cabbage. Data collected were on pest prevalence at physiological maturity, cabbage plants that survived at three weeks after planting (WAP), number of cabbage leaves damaged by insect pests at 6 (WAP), cabbage head diameter and yield of cabbages at physiological maturity. Intercropping cabbage significantly reduced pest prevalence, plant death after transplanting, leaf damage and increased cabbage yield compared to sole cabbage crop. However there were generally more benefits when intercropping with either garlic or onions between the rows than within the rows though not statistically different from intercropping within the cabbage rows at p<0.05."
