Pesticide knowledge (pesticide sales and purchase must read)

First, pesticide knowledge

Concept: Pesticide refers to the prevention or elimination of or control of agricultural and forest pests and diseases and other harmful organisms, as well as a purposeful regulation of the chemical synthesis of plants, the growth of insects or a substance derived from other natural substances of the organism or a mixture and preparation of several substances.

The use of pesticides for the control of harmful organisms is called chemical protection or chemical control. The regulation for plant growth and development is called chemical regulation.

Second, the main dosage form

Broadly includes pesticides, fungicides, nematicides, acaricides, herbicides, plant growth regulators, defoliants, desiccants, fruit thinners or mold inhibitors, and prenatal and postpartum storage and transportation processes Medium product preservative, excluding chemical fertilizers, animal and plant nutrients, food additives or animal agents.

Third, the composition of pesticides

The composition of pesticides mainly includes: main ingredient content, trade name and dosage form

Fourth, pesticide dosage form code

TC—original drug, EW—water emulsion, DP—powder, AE—aerosol, TK—mother powder, ME—microemulsion, FG—fine powder, BF—blocker, DS—dry seed dressing, OL—oil Agent, GR-granules, BR-sustained release agent, SC-suspension, GG large granules, FU-smoke agent, SD-coating agent, WS-wet seed dressing, SG-soluble granules, PF smear , AS-water agent, SP-soluble powder, WP-wettable powder, DC-dispersible liquid, EC-emulsifiable oil, WT-soluble tablet

V. Classification of pesticides

There are many varieties of pesticides and there are many classification methods. For example, it can be divided into six categories according to its use:

1. Pesticides: Pharmacy pests special control. Such as dimethoate, anti-carboside, pyrethrin and so on.

2 , acaricide: a special agent for the prevention and treatment of mites. Such as Kruth, double armor, Nisolang and so on.

3 , fungicide: a drug that inhibits and kills pathogens (such as fungi, bacteria, etc. that harm crops). Such as rice glutinous rice, Ye Yining and so on.

4 , rodenticide: killing rodenticides. Such as zinc phosphide, enemy sodium salt and so on.

5 , herbicide: herbicides in addition to weeds. Such as herbicide ether, grass can be, bentazon and so on.

6, Plant Growth Regulators: plant growth promoting or suppressing the function of starting the agent. Such as 902 (gibberellin), triacontan and so on.

6. Pesticide processing dosage form and application method

The pesticide can be processed into powder, wettable powder, creaming agent, watering agent, granule and the like, and the wettable powder and the creaming agent are used most.

The methods of using the pesticide include a spray method, a toxic soil method, a dusting method, a pouring method, a soaking or soaking method, a seed dressing method, a poison bait method, and a soil treatment method.

7. Safe use of pesticides

Chemical pesticides, although effective in controlling pests and weeds, are toxic and toxic to humans, animals and some beneficial organisms. Therefore, you must pay great attention to safety when using it and follow the safe use rules:

1, to wear rubber gloves when dispensing by measuring the amount of medication dispensed in accordance with the provisions shall be arbitrarily increase the dose.

2 , mixing medicine should be mixed with tools, how much to mix with, seeded with the application of seeds for seeding, such as hand sprinkling or on-demand, must wear rubber gloves.

3, dispensing or dressing should be in a safe place away from water sources and residential areas. It is necessary to have someone to take care of it to prevent pesticides from being lost or being eaten by people, animals and poultry.

4, should be used sprayer spraying interlacing jet, both sides can not be simultaneously spray. Stop spraying at high winds or at noon.

5, the local administration of poison is too high to be erected signs prohibiting grazing in a given period, mowing, to prevent people and livestock poisoning.

6, to ensure that the number of days from the last application harvested (safe isolation period), or pesticide residue disappeared, may cause poisoning.

Eight, identify true and false pesticides

1, powder, wettable powder: should be loose powder, no clumps, if agglomeration, uneven color, there are quality problems.

2, EC: should be a homogeneous liquid, no precipitation or suspended matter. If delamination and turbidity occur, or if there is oil slick on it, there is a sediment underneath that indicates a quality problem.

3, water agent: should be a homogeneous liquid, no precipitation, no suspension, no sticky, increased turbidity or precipitation after dilution, otherwise the quality is false.

4, suspension agent, suspoemulsion: should be a flowable suspension, no agglomeration, and some stratification, but the shaking of the logistics department should be able to restore the original shape, if shaken can not be restored to the original state, still stratified or still If there is agglomerate or mildew, the quality is false.

5, fumigation tablets: harder, do not lose powder, if powdery or soft like a fake.

6, granules: should be uniform thickness, does not contain a lot of powder, otherwise it is a fake.
