The occurrence of these conditions indicates that the purchased pesticide has been deteriorating

How to identify whether pesticides have deteriorated? Today, Xiao Bian combined several common pesticide formulations, specifically to share with you how to identify the deterioration of pesticides, I hope to help you.

1

Wettable powders.

Take 1 part of the wettable powder, add 200 parts of water, and put it in a glass. Shake well and wait for a certain period of time to observe the suspension. If the drug precipitates slowly, it indicates good suspension.

In case of poor quality, silicone additives or 0.10% neutral laundry detergent should be added before use to increase moisturizing performance. If the wettable powder binds to a hard block, it should not be used as a spray.

2

powder.

Powder in the storage process if the absorption of moisture agglomeration, you need to be placed in a cool well-ventilated place to dry not sun, crushed before use, if the agglomeration is more serious, can only be used for toxic soil.

3

EC.

In the course of custody of emulsion pesticides, if the storage is poor, the following three conditions may occur.

1, agglomeration phenomenon. If the emulsifiable concentrate has been a non-flowable viscous liquid or has formed a soapy solid, it is proved that the solvent has mostly volatilized and the quality has changed and cannot be used.

2, precipitation crystallization phenomenon. For long-term storage of the emulsion, white crystals or turbid substances may appear on the bottom of the bottle. If its cream bottle is immersed in warm water of 30-40°C, the crystals can be dissolved in about 30 minutes to return to a transparent liquid, indicating that the quality is good and can be used. If it does not dissolve, it indicates that the quality of the emulsifiable concentrate has changed and cannot be used.

3, emulsion emulsifying properties change. Take 1 part of EC, add 200 parts of water and place it in a glass. Shake well and wait for about half an hour. Observe the emulsification. If there is no slick in the upper layer, there will be no sediment in the lower layer and no oil bead in the middle, indicating good emulsification performance; There is emulsifiable concentrate, there is sedimentation, there is stratification after 10 minutes, indicating that the emulsion is destroyed can not be used.

Manual Video Measuring Instrument

Manual image measuring instrument is a precision measurement instrument that uses manual driving for 3 axes, and the measurement software is manual point taking.

This instrument uses a zoom objective to magnify the measured object, and the image is input into a computer through a CCD industrial camera device. The enlarged image of the measured object is transmitted to the measurement software for non-contact and efficient geometric measurement of various complex workpieces.

Suitable for non-contact measurement of stamped parts, plastic parts, thin film shaped, easily deformed, easily damaged, and small-sized workpieces, such as workpiece measurement in industries such as rubber, plastic, small hardware, clocks, and light industry.Video Device

.

The manual image measuring instrument consists of three parts: an image acquisition device, a data acquisition device, and a two-dimensional measurement software. The zoom objective lens and high-resolution color camera form an image acquisition device, and the data acquisition device is composed of a grating ruler and a data processor. The image and data are measured using 2D measurement software to achieve point, line, arc, and distance measurements.
