The present disclosure is generally directed to a mold inhibiting composition. The mold inhibiting composition can be used to treat various different substrates, including building material products, such as facing layers for wallboard. In general, any suitable paper product may be treated with the composition. The composition contains a mold inhibiting agent in combination with a defoamer. The mold inhibiting agent may comprise a pyrithione. The defoamer, on the other hand, may comprise an oil based defoamer containing metal oxide particles, such as silica particles. The mold inhibiting composition can be combined with a water repellent and applied to a substrate without excessive amounts of foam or froth being formed. The defoamer is selected so as to not interfere with the resulting water absorption properties of the product.

Methods of and systems for controlling dosing of drainage aid and optionally defoamer to brown stock of a brown stock washing process are provided. Certain embodiments of the invention provide independent control of drainage aid and/or defoamer to brown stock, which tends to provide improved efficiency in dosing each of the drainage aid and the defoamer.

An agricultural paper mulch sheet including a paper based substrate and a nutrient additive. The nutrient additive may be a water soluble nitrogen fertilizer. The agricultural paper may be deployed from rolls and draped over crops in a garden or field, wherein the agricultural paper covers a substantial portion of the soil in which the plants will grow or are growing, while, in some preferred embodiments, providing openings (i.e., holes) for individual plants to emanate from the soil through the agricultural paper set forth around the plant. The sheet is preferably porous, tillable, and biodegradable. The substrate may have an ink pattern printed on it. The method includes applying the nutrient additive to the substrate preferably via a printing process.
