Cultural Control
24
Cultural practices of major economic crops

26
unit of measurement of toxicity
amount (volume or weight) of the toxicant per body weight of organism (example: microgram/kg)

Acid equivalent
28
general term referring to substances added during formulation or during mixing into spray tank to improve the performance of the pesticide.

Carrier
30
material used to counteract the chemical characteristics of the AI which may normally cause phytotoxic effects.
Safener
31
surface-active agents or coupling agents. It favors or improves the emulsifying, dispersing, spreading, wetting or other surface modifying properties of liquids.
Surfactant
32
material which keep particles away from each other to prevent flocculation and to assure dispersion and to regard settling of a solid within a liquid.
Deflocculating agent
33
a surfactant that promotes the suspension of one liquid in another.
Emulsifying agent
34
surfactant that cause foaming
Foaming agent
35

Spreader
36
increases adhesion to substrates; adhesive material increases the tenacity of substances
Sticker
37
physical form of pesticide in the market is called _________ also referred to as formulation.
formulated product (FP)
38
- refers to the number of parts by weight or volume of a constituent in 100 parts of the final mixture by weight or volume.
percent concentration
39
refers to the number of parts by weight or volume of a constituent in 1 million parts of the final mixture by weight or volume.
parts per million (ppm)
40
renders the FP easy to measure, mix, safer for users, and at the same time makes the AI effective by increasing penetration and selectivity.
inert ingredient(s)
41
surfactant to reduce interfacial tensions and causes spray solutions or suspensions to make better contact with created surfaces.
Wetting agent
42
the pesticide as it is first manufactured by the company before formulation; it is almost pure.
Technical material
43
poison; the chemical in a pesticide formulation that can injure or kill the pest as well as human beings, animals or plants.
Toxicant
44
need to be mixed with water
Sprayable formulations
45
Under solid forms, AI is not water soluble, and coated with negative charge dispersant
Wettable Powder (WP)
46
Under solid forms, basically aggregated WP that disintegrates in water
Water Dispersible Granules (WDG) or Dry Flowable (DF)
47
Under solid forms, AI is water soluble

49
Under Liquid Forms,basically a wettable powder pre-mixed with a liquid inert before packaging.
Suspendable Concentrates (SC) / Liquid Flowables (LF) / Liquids (L)
50
Under Liquid Forms, Can be applied directly but it is costly so can be dissolved in lowcost solvent (kerosene or fuel oil)

Under Liquid Forms, are formulations designed to be applied at very low volumes per hectare. Volumes of about 4 liters/ha or lower can be applied using a ULV applicator
ULV concentrates
52
solid fine particle formulations usually contain 4 to 10 percent active ingredient. Some pesticides are seldom formulated as dusts due to drift problems.
Dust (D)
53
AI is combined with inert ingredients and/or carriers (clay or any suitable material) formed into particles about the size of coarse sugar or pellets. It is released by moisture to be taken up by the plant roots. Pellets are very similar to granules.
Granule (G)
54
solid or liquid; Contains a small amount of dry active ingredient mixed with food or some other attractant
Bait
55
A.i is dissolved in a volatile, petroleum solvent, or suspended in a container under pressure. Deliver the A.i. to the target site in the form of mist of small particles.
Aerosol
56
AI and diluent are ground to near colloidal dimensions, suspended in a small amount of liquid.
