Pesticide Use
Global pesticide use reached 3.5 million tonnes of active ingredient in 2022 — a 50% increase since 2000. Glyphosate alone accounts for ~1.0 Mt, the most-used pesticide in history. Pesticide intensity (kg/hectare) varies more than 100-fold across countries — from very low in sub-Saharan Africa to over 10 kg/ha in some intensive horticultural regions.
Key insights
Herbicides dominate the market
Of total pesticide active ingredient sold, herbicides (kill weeds) make up roughly 50%; insecticides 25%; fungicides 20%; other (rodenticides, nematicides, plant growth regulators) ~5%. Glyphosate has been the single largest active ingredient for over two decades — partly because of widespread genetically engineered glyphosate-tolerant crops (corn, soy, cotton).
Several major classes face restrictions
Neonicotinoid insecticides have been restricted by the EU since 2018 over pollinator harm. Chlorpyrifos was banned in the EU (2020) and many US uses (2022). Paraquat is restricted in 30+ countries but still widely used in the US and parts of Asia. Atrazine is banned in the EU but remains a US workhorse herbicide. Pesticide regulation lags the science consistently — registrations made before modern toxicology methods are common.
Pesticide intensity, not use, is the right comparison
Total use depends on farmed area. Pesticide intensity (kg active ingredient per hectare) is the better comparison. The Netherlands and Belgium use ~9 kg/ha (intensive horticulture); the US ~3 kg/ha; sub-Saharan Africa 0.2 kg/ha. Higher intensity doesn't always mean worse environmental outcomes — modern low-dose pesticides have replaced earlier high-dose chemicals. But intensity correlates with non-target effects, soil residue and pollinator exposure.

Key Finding: Continuous growth driven by area expansion in soy, maize and cotton-producing regions.

Key Finding: Intensive horticultural countries lead; extensive grain producers and sub-Saharan Africa use far less.
Methodology & caveats
Active ingredient vs formulation
Pesticide statistics usually report kg of active ingredient, not kg of formulated product (which includes solvents, adjuvants, surfactants). Trade comparisons should use active ingredient. Some older series report formulation mass; trends in active-ingredient mass have been remarkably stable while formulated mass declined as products became more concentrated.
Toxicity is not measured by mass
A pesticide's hazard is its toxicity (LD50, chronic toxicity, environmental persistence) times its exposure (application rate × persistence × non-target movement). Modern low-rate insecticides (neonicotinoids, diamides) require 10–100× less mass for the same effect than older products (organophosphates). 'Kg/ha' is therefore an imperfect proxy for environmental impact — Hazard Quotient and Pesticide Load Index are better but harder to compute internationally.
Organic farming numbers
Certified organic farmland covers ~75 million hectares — about 1.5% of world farmland (FiBL/IFOAM 2024). Concentrated in Europe (Spain, France, Italy, Germany), Argentina and India. Organic certification doesn't mean zero pesticide use — copper sulphate, neem, pyrethrins, sulphur and several others are permitted. The 'organic vs conventional' productivity gap is real but smaller than often quoted (~20–25% lower yields on average).
