There are not many opportunities of applying pesticides in winter, or even no opportunity. Some peasant households are still not yet used up the pesticides they bought, so, how to properly deposit them to avoid volatilization and loss of effectiveness, and prevent the occurrence of people and domestic animals intoxication accidents.

a. Read operation instructions carefully before depositing the remaining pesticides. Deeply buried the expired pesticides, and do not litter and strew.

b. Store the label and the operation instructions well, and timely updates the damaged packages like bottles and bags. Do not forget to seal the wettable powder pesticide to prevent caking and loss of efficacy after moisture absorption. As for the pesticides that have lost their labels or with vague labels, it is necessary in order to rewrite the name, directions, dosage, expiry date, and range of application on paper, and stick them on the bottle or bag for correct use.

c. Seal should be noted. DDVP, dimethoate, octyl mercaptan, and other pesticides are easy to volatilize and lose efficacy, being expected to result in air pollution. The bottle cap must be tightened up and sealed while storage.

d. Temperature should be maintained. Under high temperature, the quality of most of the powder pesticides is easily affected. The higher the temperature, the easier the pesticide will melt, decompose, volatilize, even combust or explode. The emulsifiability of some emulsion pesticides are easily destroyed under elevated temperature, which reduces its efficacy. Under low temperature, some bottled liquid pesticides are susceptible to ice up, forming clumps, and make the bottle frost-cracked. The indoor temperature should be kept over 1°C. In addition, Octyl mercaptan pesticide is not to be exposed to light. Long-term exposure to light will lead to the decomposition and degeneration of the pesticide, will no longer be effective. Therefore, high temperature and insolation should be avoided while storage.

e. Keep dry. Powder pesticide and plant growth regulator are susceptible to moisture absorption and caking. Consequently, place of depositing pesticide should be kept dry and be strictly on guard against rain or snow. Be sure to open the window to ventilate and keep the relative humidity under 75%.

f. Store by category. Pesticides can be subdivided into alkaline, acidic, and neutral. Alkaline pesticides include propanil, lime sulphur. Bordeaux mixture, and so on; acidic pesticides incorporate DDVP, ergo, desquamation, abamectin insecticide, etc.; neutral pesticides contain editorials, and so forth. These three kinds of pesticides that are of different natures should be kept separately with distance of over 0.5 meters while storage. Otherwise, the pesticides will interplay, causing degeneration and failure. In addition, don’t put two different types of pesticides that have not meant used up into the same bottle, or they will lose efficacy.

g. Pay attention to the prevention of accidents. All pesticides have virulence of discrete levels. It is better to store them into an exclusive cabinet or wooden case, and lock from the outside. Pesticides are not to be deposited together with grain and oil, beans, seed, and vegetables in the same room; emulsifiable concentrate and fumigant pesticides should not be placed together with inflammables and explosives, such as match, engine oil, firecracker, and so on. It should not be stored near people, livestock, or birds. Keep this out of the reach of children to avoid accidents.
