Includes insecticides, herbicides and fungicides. The health hazard to humans and animals is mild with herbicides and fungicides, while greater with insecticides.
What are seed treatment fungicides?
Fungicide seed treatments provide protection against seed-borne and soil borne pathogens which may interfere with seed germination or may infect the seedling soon after germination. Nematicide seed treatments provide protection against nematodes such as soybean cyst nematode (SCN).
What are pesticides called that are applied to seeds before planting?
Seed treatment pesticides include bactericides, fungicides, and insecticides. Most seed treatments are applied to true seeds, such as corn, wheat, or soybean, which have a seed coat surrounding an embryo.
What is pre-sowing seed treatment?
Pre-sowing seed treatment stimulates the natural conditions that allow seeds to germinate. Seeds of many plants and trees need a certain period for their immature parts to develop and their dormancy (factors preventing germination) to end, allowing for them to sprout.
What is seed dressing?
In agriculture and horticulture, seed treatment or seed dressing is a chemical, typically antimicrobial or fungicidal, with which seeds are treated (or "dressed") prior to planting. Less frequently, insecticides are added.
When were seed dressings first used?
History. The earliest seed dressings were of organo-mercurials used to control pests such as oat smut and bunt of wheat. These were available from the 1930s but were ineffective on Pythium and Fusarium species which are pathogens of many crops including cotton, maize and soya.
Can you use conventional seed?

Why do we use insecticides on seed?
Insecticides are often applied to seed to control or reduce insect damage to seed during storage and, to a lesser degree, to prevent damage from such insects as wireworms and seed corn maggots in the soil.
What are the benefits of insecticides?
Though a seed lot that meets high standards of germination, vigour and purity if it is contaminated with seed borne pathogens and insect pests, may be useless to farmers because it may result in severe yield loss or even crop loss in an entire area. Benefits of the insecticidal and fungicidal treatments: 1. Prevents the spread of plant diseases 2. It protects the seed from seed rot and seedling blights. 3. It improves the seed germination 4. It provides protection from storage insects. 5. It controls the soil insects.

Stored seed is soaked in water or solution of chemicals sufficient to cover it and kept at room temperature for 2-6 hour depending on the material with occasional stirring. The soaked seed is taken out and after surface drying in the shade for some time, dried back to the original moisture content Dilute solution of chemicals such as sodium or potassium phosphate (di and mono basic), sodium chloride, p-hydroxy benzoic acid, p-amino benzoic acid, oxalic acid, potassium lodide, etc can also be used at 10-4 to 10-3 M concentrations. Fungicidal and insecticidal formulations can also be incorporated in the soak water.
What is systemic pesticide?
Some of the systemics, a fairly new class of pesticides, may now be used as seed treatment materials. The desirability of having materials that would move inside the seed or plant and control the pest has long been recognized. Such materials are called "systemic." When used according to the manufacturer's recommendation (see label), a systemic moves through the host plant and controls or retards the growth of certain fungi and insects without affecting the host's metabolic system.

Several kinds of fungi cause seed rot, seedling rot (damping off) and seedling disease. The most common ones in Iowa are Rhizoctonia and Fusarium, the water mold fungi Pythium and Phytophthora, and seed-borne Phomopsis.
What insecticides kill bean leaf beetles?
High numbers of bean leaf beetles have created a concern about direct losses from beetle feeding injury plus losses related to bean pod mottle virus. Previously, we have been able to manage the beetles using foliar insecticides, but we do now also have an insecticide seed treatment that can be used to manage the beetles. In 2004 and 2005, Cruiser and Gaucho were registered to use as a seed treatment on soybean in United State, respectively. They are both systemic insecticides and belongs to a new subclass of neonicotinoids. They moves systemically throughout the plant and protects against target pests through contact and stomach activity. We are evaluating both Cruiser and Gaucho in different trials in combinations with different fungicides. The largeste study will be finalized after the 2007 growing season and data will then be available.
Why do seeds need to be stratified?
In nature, seeds require certain conditions in order to germinate. Seed stratification is the process whereby seed dormancy is broken in order to promote this germination. In order for the stratification of seeds to be successful, it is necessary to mimic the exact conditions that they require when breaking dormancy in nature. ...
Why do plants need cold seed stratification?

Overview
In agriculture and horticulture, a seed treatment is any additional material added to the seed. By the amount of material added, it can be divided into:
• A seed dressing, typically containing a "protectant" (pesticide) applied to the seed and possibly some color.
• A seed coating, a layer of thin film applied to the seed typically less than 10% of the mass of the original seed.
History
The earliest seed dressings were of organo-mercurials used to control pests such as oat smut and bunt of wheat. These were available from the 1930s but were ineffective on Pythium and Fusarium species which are pathogens of many crops including cotton, maize and soya. Thiram was therefore developed as a seed treatment in the 1940s to extend the spectrum of diseases that could be controlled. In 1949 ICI commercialised a seed treatment with trade name Mergamma A, …
Biocide
One seed pesticide, imidacloprid, from the neonicotinoid family of insecticides, is controversial and was banned in France for use on maize, due to that government's belief that the chemical was implicated in recent dramatic drops in bee counts, and possibly in Colony Collapse Disorder. Dust from treated seed is known to have caused at least some health and safety problems particularly from crops such as maize drilled during the main honey flows. Improvements to pneumatic drill…
Water-retainer
Water-absorbing polymers may be added around seeds to help with absorbing water dry conditions, or to delay the germination until drought has passed. It has seen some use in the industry.
Fertilizer
Seed coating may contain a dose of fertilizer, typically of plant micronutrients, but also occasionally containing slow-release macronutrients.
Inoculum
A sufficiently-thick seed coating can allow for seeds to be distributed pre-inoculated with symbiotic microbes such as rhizobia for legumes. The formulation of the coating slurry plays a huge role in maintaining the viabilitiy of these microbes. The state-of-the-art academic formulation (as of 2019) is able to maintain microbial populations for 9 months, quite a bit behind the viability of the seeds themselves. Despite these drawbacks, inocula have been used in com…
