Since 2014, the Israeli military has been aerially spraying vegetation-killing herbicides in Gaza in order to clear out the area along the Gaza border. The spraying is done by aircraft a few times a year, during December-January and again around April. The Israeli Ministry of Defense claims the spraying is done on the Israeli side of the border and refuses to disclose the exact locations for “security reasons.” However, many Palestinian farmers had their vegetable fields and crops destroyed. The Red Cross confirmed that the herbicides “completely destroyed” crops and contaminated water sources located within 3,000 feet from the border. The herbicides were also found to have damaged crops up to 1.3 miles inside the Gaza Strip. The entire width of the Gaza Strip ranges between 3.5 and 7.5 miles. During the 2017-2018 winter spraying season, the herbicides affected 544 acres of agricultural lands and 2,570 acres of pasture.

Some Palestinian farmers have sought compensation for their loss of livelihood from Israeli authorities. The Israeli Ministry of Defense rejected their demands and refused to name the chemicals it uses, but it did not deny that the damages were a result of its spraying activities. Beyond the economic loss of the harvest, the herbicides are also harmful to human health and to the environment, as detailed below. In a similar case, Israeli authorities used aerial spraying to destroy the crops of of Palestinian Bedouin Israeli citizens until 2007, when the Israeli Supreme Court banned this practice because of its danger to human life and health. Today, the Israeli military coordinates the spraying with the Israeli communities that surround the Gaza Strip, for them to take measures to minimize the harm, but does not give comparable advance notice to farmers in Gaza.

A freedom of information application, filed by Israeli human rights organization Gisha, revealed the chemicals used and the companies involved. The spraying is executed by two Israeli civilian aviation companies, Chim-Nir and Telem Aviation, at the direction of the Israeli military’s Gaza Division. The contract with the aviation companies indicates the specific brands of herbicides to be used:

  • Glyphosate (Roundup) - produced by U.S.-based company Monsanto, a subsidiary of German pharmaceutical giant Bayer. In 2015, the International Agency for Research on Cancer classified Glyphosate as a probable human carcinogen. In 2018, a U.S. court ordered Monsanto to pay $289 million to a California resident because his cancer was found to be caused by Roundup. Monsanto faces thousands of similar lawsuits in the U.S. alone.
  • Oxyfluorfen (Goal) - produced by U.S.-based company Dow Chemical, now part of DowDuPont (NYSE: DWDP), the world's largest chemical company in terms of sales. The U.S. Environmental Protection Agency classifies oxyfluorfen as a possible human carcinogen since 1992. The U.S. Department of Agriculture found Oxyfluorfen to be a health hazard for anyone handling it without protective gear or consuming food contaminated with the herbicide.
  • Diuron (Diurex) - produced by Israeli company ADAMA Agricultural Solutions (formerly Makhteshim Agan Industries), a subsidiary of ChemChina - the state-owned China National Chemical Corporation. The U.S. Environmental Protection Agency has found Diuron to produce “dioxin-like effects,” i.e. reproductive and developmental problems, harm to the immune system, and cancer.

The same chemicals are manufactured by other companies as well, and we don't have evidence that the above companies' products are the ones being used in this case.

This is not the first time chemicals produces by these companies are weaponized. DuPont, initially a gunpowder and explosives manufacturer and now part of DowDuPont, was the largest supplier of gunpowder to the U.S. military during the American Civil War. Dupont later became part of the Manhattan Project, producing plutonium for the atomic bomb the U.S. dropped on Nagasaki. During the Vietnam War, both Monsanto and Dow Chemical were leading providers of “Agent Orange” to the U.S. military, which sprayed it over the jungles of Vietnam, Laos, and Cambodia, causing massive environmental damage and lingering public health problems. Dow Chemical also produced napalm for the U.S. military to use in Vietnam.

More recently, Monsanto was revealed to be a leading manufacturer of weaponized white phosphorus. A 2012 U.S. Army procurement document named the company as the sole U.S.-based manufacturer of white phosphorus for M110 chemical artillery projectiles. International humanitarian law restricts the military use of white phosphorus due to its incendiary properties. During its 2008-2009 assault on Gaza, the Israeli military used U.S.-made white phosphorus shells illegally, in areas heavily populated with civilians. However, a Human Rights Watch found ammunition remnants that were manufactured two decades earlier by Thiokol Aerospace, a U.S. company now part of Northrop Grumman, not by Monsanto.


While herbicides do not qualify as “chemical weapons,” Israel’s use of them  in Gaza may constitute a violation of international humanitarian law. In general, international humanitarian law requires that, during wartime and occupation, civilians and humanitarian interests must be protected. Customary international humanitarian law severely restricts the use of herbicides as in warfare. Herbicides must not be used against vegetation which is not a military target, if it causes excessive incidental damage to civilian objects, or if it could cause widespread, long-term, and severe damage to the natural environment.

The detrimental use of herbicides needs to be understood in the context of the decade-long military blockade imposed by Israel on the Gaza Strip. In 2017, the UN estimated that more than 40 percent of the population in Gaza was food insecure, mainly as a result of the blockade. By destroying crops year after year, Israel may be in violation of Article 55 of the Fourth Geneva Convention, which requires an occupying state to ensure the food supplies of the occupied population. In addition, customary international humanitarian law prohibits the use of starvation as a method of warfare and prohibits attacking “objects Indispensable to the survival of the civilian population.” Under the blockade, local produce has become one of the main sources of sustenance and livelihood for Palestinians in Gaza.
